biasing
B-004-02-03:
The primary purpose of a Zener diode is to:
regulate or maintain a constant voltage
provide a voltage phase shift
to boost the power supply voltage
provide a path through which current can flow
B-004-02-04:
The action of changing alternating current to direct current is called:
rectification
amplification
transformation
modulation
