The biasing of a transistor is purely a/n ___________ operation

• AC

• DC

• both A and B

• none of the choices

The purpose of biasing is to establish a ___________ about which variations in current and voltage can occur in response to an input signal.

• DC supply

• Fixed-bias

• quiescent point

• None of the choices

Type of operation when the output signal is an amplified replica of the input signal

• Q-point

• Linear

• passive

• Non-linear

The output signal is an amplified replica of the input signal except that it is inverted and with clipped portion

• Q-point

• Linear

• . passive

• Non-linear

It refers to the use of signals that take up relatively small percentage of an amplifier’s operational range.

• large signal

• small signal

• medium signal

• none of the choices
