Single Sideband Modulation (SSB): Single Sideband Modulation (SSB) can he obtained by passing the output of a carrier suppressor (product modulator) through filter circuits that are selective to transmit one…
Types of Amplitude Modulation (AM): As we know already that, one carrier and two sidebands are produced in AM generation. However, it is not essential that all these signals are…
Output Stage of an Op Amp and its Voltage Transfer Characteristics: The output stage of an op amp is another requirement which should have very small output impedance and provide…
Direct Coupled Transistor Amplifier - Operations and Equivalent Circuit: Direct coupling is essential for very low frequency (below 10 Hz) applications such as photoelectric current, thermocouple current etc. Thermocouples are…
RC Coupled Transistor Amplifier - Operations, Derivation and Applications: A two-stage RC Coupled Transistor Amplifier using N-P-N transistors in CE configuration is shown in Fig. 16.12. The two transistors used are…
Frequency Response of RC Coupled Amplifier: The curve drawn between the voltage gain and signal frequency of an amplifier is known as the frequency response. The performance of an frequency…
n Stage Cascaded Amplifier: As already discussed, several amplifier stages are usually cascaded to increase the overall voltage gain of the amplifier. However, sometimes cascading is done to obtain the…
Miller Effect in Amplifier Frequency Response: According to this effect, when viewed from the input base terminal of the CE-connected transistor the capacitance Ccb appears as (1 - Av)Ccb i.e., it is…
