p. Bandwidth represents the range of frequencies that a circuit
will pass.
q. A pulse is a sudden rise and fall of voltage or current.
r. A pulse parameter is a characteristic property that describes
a pulse.
s. Good reproduction of a pulse during its rise and decay times
depends on the highfrequency response of the circuit.
t. Highfrequency response is determined by using the formula
u. Good reproduction of a pulse during its duration time depends
on the lowfrequency response of the circuit.
v. Lowfrequency response is determined by the prf of the input
pulse.

TYPES OF TIMERS.
The function of a timer is to ensure that all circuits
connected within an electronic system operate in a definite time
relationship with each other, and that the interval between pulses is
of the proper length. Multiplexers, which are used to increase
traffic capability in voice communication, require precise timing;
