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.
