The Digital to Analog converter is an electronic device which converts digital signal to analog signal. Weighted Resistor and R-2R Ladder are its types.

We use small signal transistor model to analyze h-parameters. A transistor can be treated as a two port terminal.

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.

The three basic transistor configuration are CE, CB and CC. A transistor is a three terminal device Emitter, Base and Collector.

Boolean algebra which deals  with variables and binary numbers. This algebra helps to simplify the Boolean variables

Superposition theorem is applicable to circuits with linear elements. They are not applicable to power since it is a non-linear quantity.

Norton’s equivalent is obtained by source conversion of Thevenin’s equivalent circuit. The short circuit current is then given as Isc=Vth/Rth

FFT algorithms are based on the fundamental principle of decomposing the computation of DFT of sequence length into successively smaller DFT

TDMA (Time division multiple access) is used where there is no need for continuous transmission. Due to this it can be used instead of FDMA.

A Servo motor is similar to an induction motor having two primary windings placed 90 degrees apart in magnetic position.

The Fourier transform states that non-periodic signal having finite area under the curve can be represented into integrals of sine and cosine

The circuit which produces the samples of the input voltage and holds those values for a definite amount of time is sample and hold circuit.

A function is said to be positive Real function if it has all the poles and zeros on the left half of the S-plane. Re[ H(jw) ] >=0 for all ‘w’

The precision rectifier has the capability of rectifying voltages which are of smaller magnitude than the forward voltage drop.

An interrupt is a condition that arises during the working of a microprocessor. The interrupts of 8086 initiate interrupt service through ISR
