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.
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
The concept of data communication in GPRS is similar to the GSM network. GPRS has data rates of 9.6 to 171 kbps.
The multiplexer is a special type of combinational circuit which has n-data inputs, one output and m inputs select lines with 2^m = n.
The convolution theorem states that the transform of convolution of f1(t) and f2(t) is the product of individual transforms F1(s) and F2(s).

The K-Map is used to simplify the Boolean Functions in a very easy way. The K-Map was introduced by Karnaugh.
The Switched mode power supply is abbreviated as SMPS is used to convert the regulated DC output voltage from unregulated DC or AC voltage.
Frequency Modulation is the technique in which the frequency of a carrier signal is varied according to the message signal.
ZigBee forms the upper layer for control and sensor applications. It is built above IEEE 802.15.4.
