Testing and Troubleshooting - Technical MCQs

Q1:

Often a common-collector will be the last stage before the load; the main function of this stage is to

A provide voltage gain

B buffer the voltage amplifiers from the low-resistance load

C provide phase inversion

D provide a high-frequency path to improve the frequency response

ANS:B - buffer the voltage amplifiers from the low-resistance load

Common-collector is basically a voltage follower or buffer device.
