Q. Explain Resistance-capacitance coupling?
It is the most commonly used coupling in discrete device amplifier as it is least expensive and has satisfactory frequency response. In this method the signal developed across the collector resistor Rc of each stage is coupled through capacitor Cc into the base of the next stage of one stage from the following stage. The amplifiers using this coupling scheme are called RC coupled amplifiers.
Consider the circuit in Figure (a), which include a controlled source, and find the current in the 5-V source and the voltage across the 5- resistor by using (a) the loop-current
Explain the Synchronous Compensators These are synchronous motors running without mechanical loads (or with load if required). Similar to the synchronous generators, they can a
Q. What is the advantage of using JFET as an amplifier? As an amplifier of small time-varying signals, the JFET has a number of valuable assets. First of all it has a very high
