# What is Digital to Analog Converter?

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.

# What is the CB Hybrid Model?

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

# What is Block Diagram of TV Communication?

The block diagram of a TV communication system consists of a TV transmitter and a receiver. The transmitter consists of two units.

# What is Minimum Mode Configuration of 8086?

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.

# What are CE CB CC transistor configurations?

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

# What is Boolean Algebra?

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

# What is the Superposition Theorem?

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

# What is Norton’s Theorem?

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

# What is FFT?

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

# What is TDMA?

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.

# What is Servomotor?

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

# What is Fourier Transform?

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

# What is the need of a Sample and Hold Circuit?

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.

# What is a Positive Real Function?

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’

# What is a Precision Rectifier?

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

# What are the Interrupts of 8086?

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