The term human–computer interaction (HCI) is used widespread since early 1980s. Second World War provided impetus …
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.
Superposition theorem is applicable to circuits with linear elements. They are not applicable to power since it is a non-linear quantity.
An interrupt is a condition that arises during the working of a microprocessor. The interrupts of 8086 initiate interrupt service through ISR
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 MOSFET (Metal Oxide Semiconductor Field Effect Transistor) transistors are used for switching and amplification.
The clipper circuits are basically used to clip the portion of any input signal without changing the remaining part of the input waveform.
The K-Map is used to simplify the Boolean Functions in a very easy way. The K-Map was introduced by Karnaugh.
The concept of data communication in GPRS is similar to the GSM network. GPRS has data rates of 9.6 to 171 kbps.
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.
