Wein Bridge Oscillator using Op Amp: The Wein bridge is an ac bridge that balances only at a particular supply frequency. In the Wein Bridge Oscillator using Op Amp (Fig.…
Colpitts Oscillator using Op Amp: The Colpitts Oscillator using Op Amp circuit show in Fig. 16-4 is similar to the op-amp phase shift oscillator, except that an LC network is…
RC Phase Shift Oscillator Circuit Diagram: Figure 16-1 shows the RC Phase Shift Oscillator Circuit Diagram, which consists of an inverting amplifier and an RC phase-shifting network. The amplifier phase-shifts…
Stray Capacitance Effects: Stray Capacitance Effects (Cs) at the input terminals of an operational amplifier effectively introduces an additional phase-lag network in the feedback loop, (see Fig. 15-17), thus making…
Voltage Series Negative Feedback Amplifier: In a negative feedback amplifier, a small portion of the output voltage is fed back to the input. When the feedback voltage is applied in…
Generation of Frequency Modulation: The Generation of Frequency Modulation system is a variable output frequency, with the variation proportional to the instantaneous amplitude of the modulating voltage. The subsidiary requirements…
Methods of Suppressing Unwanted Sidebands: As stated earlier, the three practical methods of SSB generation all use the balanced modulator to suppress the carrier, but each uses a different method…
Unsymmetrical Fault Articles: Unsymmetrical Faults on Three Power System: Those faults on the power system which give rise to unsymmetrical fault currents (i.e. unequal fault currents in the lines with…
