Heterodyne Wave Analyzer: Wave analyzers are useful for measurement in the audio frequency range only. For measurements in the RF range and above (MHz range), an ordinary wave analyzer cannot…
What is Signal Generator?: What is Signal Generator? : A signal generator is a vital component in a test setup, and in electronic troubleshooting and development, whether on a service…
True RMS Voltmeter: True RMS Voltmeter - Complex waveform are most accurately measured with an rms voltmeter. This instrument produces a meter indication by sensing waveform heating power, which is…
Average Responding Voltmeter and Peak Responding Voltmeter: A simplified version of a circuit used in a typical average responding voltmeter is given in Fig. 4.23. The applied waveform is amplified…
Solid State Voltmeter: Solid State Voltmeter - Figure 4.13 shows the circuit of an electronic voltmeter using an IC OpAmp 741C. This is a directly coupled very high gain amplifier.…
Automatic Voltage Control: Automatic Voltage Control - Figure 8.20 gives the schematic diagram of an automatic voltage regulator of a generator. It basically consists of a main exciter which excites…
Load Frequency Control of Single Area System: Let us consider the problem of controlling the power output of the generators of a closely knit electric area so as to maintain…
Two phase AC Servo Motor: For a low-power (a few hundred watts) control application, a balanced Two phase AC Servo Motor is ideally suited as it can be driven by…
