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.
