filter
a circuit which allows signal of certain frequen-
cies
to pass through unaltered, while preventing passage
of
other signal frequencies.
forward
biased
a diode is forward biased when its an-
ode is at a more positive potential than its cathode.
frequency the number of
cycles
of a periodic signal in
a
given time. Usually frequency is measured in
cycles
per second, or Hertz (shortened to Hz).
frequency
response
curves
graphs of a circuit's gain
against the frequency of the applied a.c. signal.
full-wave
rectification rectification of an a.c. voltage to
d.c, where both half-waves of the a.c. wave are recti-
fied.
