The block diagram of a TV communication system consists of a TV transmitter and a receiver. The transmitter consists of two units.
-
The microprocessor 8086 minimum mode and maximum mode operation is decided by signal MN/MX’. When the signal MN/MX’ = 1 the 8086 minimum mode is active.
-
We use small signal transistor model to analyze h-parameters. A transistor can be treated as a two port terminal.
-
Boolean algebra which deals with variables and binary numbers. This algebra helps to simplify the Boolean variables
-
The three basic transistor configuration are CE, CB and CC. A transistor is a three terminal device Emitter, Base and Collector.
-
Norton’s equivalent is obtained by source conversion of Thevenin’s equivalent circuit. The short circuit current is then given as Isc=Vth/Rth
-
Superposition theorem is applicable to circuits with linear elements. They are not applicable to power since it is a non-linear quantity.
