Q. What do you understand by common control?
In some switching systems, control subsystem may be an integral part of switching network itself. Such system iscalled direct control switching systems. Those systems in which control subsystem is outside switching network are called common control switching system. Stronger exchanges are generally direct control systems while crossbar and electronic exchanges are common control system. All stored program control systems are common control systems. Common control is also called register control orindirect control.

Q. What is a clipper circuit? Clipping circuits are linear wave shaping circuits. The main function of 'clipper' is that it clips off a part of input waveform i.e., it cut off
Clipper Circuits: Clipper circuit have ability to Clipper of portions of the input signals without distorting the remaining part of the alternating wave form. Clamper net

Q. What is Barkhausen criterion? Why is the value of Ab kept slightly greater than 1? The condition |Ab| = 1 is called the Barkhausen criterion. It implies that when |Ab| = 1,
