This article has been cited by other articles in PMC. It monitors a three phase electrical system using an Arduino platform as a microcontroller to read the voltage and current from sensors and then wirelessly send the measured data to monitor the results using a new Android application. The Arduino Nano V3. The new Android smartphone application that monitors the voltage and current measurements uses the open source MIT App Inventor 2 software. It allows for monitoring some elementary fundamental voltage power quality properties. An effort has been made to investigate what is possible using available off-the-shelf components and open source software. Introduction Because of the increasing advances in technology, smart systems are increasingly being used.
Rf Figure 2 Graphic equalizer circuit. For example, if your favorite music is jazz, do some research and find out what frequency ranges you are most likely to want to amplify or attenuate based on your favorite musical instruments.
Each of the LC combinations specifies a resonance frequency for the graphic equalizer. When the audio signal has a frequency component that corresponds to one of the resonance frequencies, the impedance of that resonance circuit is at a minimum value for that component of the audio signal, and is then either amplified or attenuated, depending on the position of the potentiometer.
To understand the basic operation of this circuit, it is suggested that you first experiment with designing the gain for the circuit in Figure 3.
Use a value of r that is sufficiently small compared to the resistance of the potentiometer, R. Analyze the circuit, build it, and confirm your analyses. Then replace the small resistor r with a series LC impedance. Now test the circuits frequency response by connecting it to you function generator, sweeping the frequency throughout the audio range, and taking measurements of the response.
After you have one band of your Lab 2: Audio Amplifier and Graphic Equalizer Design using Opamps equalizer working, add the other two potentiometers and LC impedances and then again sweep the frequency and take measurements. Be sure to check the potentiometers and make sure that they either attenuate or amplify the signal at the LC resonant frequencies you chose. It is strongly recommended that you use SPICE as part of your analysis, and run several circuit simulations before coming to lab.
When you have completed your circuit and verified its functionalVin vout R r Figure 3 Simplified Graphic equalizer circuit. Please DO NOT disassemble your circuit after lab is over because you will need it for the following week. Week 2: Power Amplifier Design a power amplifier circuit using the LM power opamp data sheets are appended to this lab.
The ability to drive an 8 ohm speaker load. The entire circuit, when assembled with the graphic equalizer, maintains input signal polarity. It is extremely important that you use a heat sink with the LM power amp. Why do you think it is necessary? Test your amplifier circuit first by applying a 1kHz sinusoidal input signal.
Note the use of a node voltage probe and the signal name allocated by Qucs. Also note that the individual capacitor voltage and inductor current initial conditions are not set as they are not needed due to fact that the filter subcircuit is not DC biased.
As a consequence the DC simulation icon shown in Figure 3. However, its a good idea to add it automatically to AC simulations because circuits with semiconductor devices or other non-linear components must have their small signal AC properties calculated, at their DC bias conditions, prior to small signal AC simulation.
The extent to how this will affect the operation of spice4qucs is at this time unclear. The Xyce circuit simulator does not include a version of Nutmeg in its distribution package.
This implies that Nutmeg style post simulation data processing is not possible with Xyce. PRINT statement has been implemented in Xyce, allowing algebraic expressions for data processing to be embedded in.
PRINT statements. This topic and other aspects of Xyce post simulation data processing are covered in later sections of this help manual. This form of subcircuit can, for example, be used to represent manufacturers product variations which have identical circuits but require component values or device parameter values of differing value. One consequence of this is that over time divergence of the SPICE subcircuit statement syntax has occurred amongst different circuit simulators.
This works well, but does have one disadvantage however, in that some published subcircuit netlists may require a small amount of editing before they will simulate with Spice4qucs. This can occur in an X subcircuit call to signify a subcircuit with parameters.
As an introductory example Figure 3. The Qucs Equation block, at the subcircuit internal circuit level, is used to calculate the individual harmonic frequencies. For clarity long Qucs netlist lines have been spread over more than one line. A casual look at these two subcircuit diagrams shows that they are not dissimilar. However, there are a number of subtle changes apparent from the diagrams. In Figure 3. Finally, it is important to realize that the order of the variables in Equation blocks are important.
Qucs allows them to be in any order because it arranges all entries into a sequence which ensures each variable can be allocated a numerical value before it is used in other equations. However, SPICE does not do the same but assumes that all variables included in the right hand side of an equation have been allocated a numerical value prior to being used in the calculation of the variable named on the left hand side of the same equation.
PARAM statements. These are listed in the initial section of the SPICE-netlist of the circuit being simulated, or in the first section of a subcircuit netlist, allowing their values to be determined before the start of a simulation.
Restrictions placed by Spice4qucs on the use of Qucs Equation Eqn blocks are considered in detail in Chapter 4. However, one fundamental rule that must be followed at all times is that Qucs simulation icons must not be placed inside a subcircuit. In this model the crystal resonator is represented as the RCL parallel electric network illustrated in the following two schematics: quarz. V OUT. The only difference being that Xyce simulation result postprocessing is not implemented.
Hence, only the Xyce output voltage can be plotted; this is done by choosing a logarithmic Y scale, then the Xyce plot effectively displays a scaled decibel output. END 3.
You can use all library components. You should prefer to use these libraries to archive the best result with Spice simulation of Qucs schematics. You need to perform the following steps to use Spice-model from component datasheet.
