Finding a circuit to change the relationship between the waveform and the zero-volt axis and calculating the period of the waveform.
1. To change the relationship between a waveform and the zero-volt axis, and at the equal time retain the shape of the wave, you would use a
A) Toggled flip flop
B) d-c restorer
C) Limiter
D) Clipper
2. If the pulse repetition rate (PRR) of a transmitted pulse is 400pulses per second, what is the period of the waveform?
A) 2.5 msec (microseconds)
B) 4.0 msec (microseconds)
C) 25 msec (microseconds)
D) 40 msec (microseconds)
