Difference between multiplexer and demultiplexer

Multiplexer processes the digital information from various sources into a single source. Demultiplexer receives digital information from a single source and converts it into several sources It is known as Data Selector It is known as Data Distributor Multiplexer is a digital switch Demultiplexer is a digital circuit It follows combinational logic type It also follows combinational logic type It has n data input It has single data input It has a single data output It has n data outputs It works on many to one operational principle It works on one to many operational principle In time division Multiplexing, multiplexer is used at the transmitter end In time division Multiplexing, demultiplexer is used at the receiver end

Explain avalanche breakdown with respect to PN junctions.

An electrostatic CRT has parallel deflection plates 1.5 cm long and 6mm apart. The screen is 55cm from the centre of the deflecting plates. The deflecting and accelerating potentials are 150 V and 2.5 kilovolts respectively. Determine the:
