Common Collector Configuration-Emitter Follower (u sing Darlington pair)-Gain and input impedance measurement of the circuit. 7. Power Amplifiers-Push pull amplifier in class B mode of operation –measurement of gain. 8. Frequency response of Common Emitter Amplifier: Emitter bypass capacitors are used to short circuit the emitter resistor and thus increases the gain at high frequency. The coupling and bypass capacitors cause the fall of the signal in the low frequency response of the amplifier because their impedance becomes large at low frequencies. times its value at 10 KHz. The frequency at which this happens gives you the Lower Cut-off frequency (f1). 7. Keeping the input voltage constant, go on increasing the frequency until the output voltage decreases to times its value at 10 KHz. The frequency at which this happens gives you the Upper Cut-off.
