Question

dc bias establishes the dc operating point for an amplifier.
select one:
○ true
○ false

Explanation:

DC bias in an amplifier sets the DC operating point (quiescent point). It ensures proper transistor operation (active region for BJT, saturation region for FET) by providing correct DC voltages and currents. Without DC bias, the amplifier may not function correctly (e.g., distortion due to improper transistor biasing). So the statement is correct.

Answer:

True
