PULSE DIGITAL CIRCUITS
1. The
process where by the form of a non-sinusoidal signal is altered by transmission
through a linear network is called Linear
wave shaping.
2. The
process of converting pulses into pips by means of a circuit of short time
constant is called peaking.
3. A
circuit which clamps the positive peak of a signal to zero level is called Negative clamping circuit.
4. The
time required for the stored minority charge to become zero after the
application of the reverse voltage is called the Storage time.
5. A
transistor acts as an amplifier when it is in Active region.
6. A
circuit which can oscillate at a number of frequencies is called a Multivibrator.
7. The
required for the recharging of capacitors after the transfer of conduction is
called the settling time.
8. The
ratio of the difference in slope at beginning and end of the sweep to the
initial value of slope is called the slope
error or sweep speed error.
9. The
Multi Vibrators, time-base generators, blocking oscillators are the examples of Relaxation
circuits.
10. The
gain of a sampling gate is defined as the
ratio of the output voltage to the input voltage during transmission.
11. Logic gates
are the fundamental building blocks of digital systems.
12. MOS
family most uses NMOS devices.
13. The
fastest logic family is ECL.
14. Both
Mono stable and Astable blocking oscillators are used to generate pulses of
High peak power.
15. A
blocking oscillator uses Regenerative
feedback.
16. Mono stable
blocking oscillators require triggering.
