In PAM, amplitude of pulses is varied in accordance with the instantaneous value of modulating signal. It is basic technique for all modulation
The Delta Modulation has step size much smaller after quantization and also the sampling rate is much higher.
When a semiconductor is doped with half of the trivalent impurity and other half with pentavalent impurity is then called PN junction diode
The clipper circuits are basically used to clip the portion of any input signal without changing the remaining part of the input waveform.
CMOS is a new type of MOSFET logic is made combining both the PMOS and NMOS processes and is called complementary MOS.
The amplitude of the carrier signal varies in accordance with the instantaneous amplitude of the modulating signal in Amplitude Modulation.
Frequency Modulation is the technique in which the frequency of a carrier signal is varied according to the message signal.
There are three operational amplifiers in the circuit of an Instrumentation Amplifier of which two non inverting amplifiers are the inputs.
It is a DC motor which rotates in steps. After the electrical signal is fed to the motor, it starts to rotate in steps. The speed of the motor is dependent on the rate of input signal applied. The input applied to the motor decides the direction of rotation of the motor. The rotor is a permanent magnet which rotates.
FFT algorithms are based on the fundamental principle of decomposing the computation of DFT of sequence length into successively smaller DFT
The term human–computer interaction (HCI) is used widespread since early 1980s. Second World War provided impetus …
In order to make communication more safer and reliable digital signals are used. The basic digital modulation techniques are ASK, PSK,FSK and MSK
The DC Motor is an electrical machine which can be classified as Separately excited DC Motor, Permanent Magnet and Self excited DC Motor.
Addressing modes are used to specify the data to be operated with the help of instructions.
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.
