The amplitude of the carrier signal varies in accordance with the instantaneous amplitude of the modulating signal in Amplitude Modulation.
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.
Crystal Oscillator is specially designed in a circuit to provide low impedance when it operates in series-resonant mode and high impedance.
Wien bridge oscillator is an audio frequency sine wave oscillator of high stability and simplicity with no phase shift in feedback network.
Synchronous counter is designed to count the number of clock pulses. This counter is clocked with the same clock signal and at the same time
The basic working of an induction motor is producing a rotating magnetic field and this field is sinusoidally distributed.
The 8255 microprocessor is also known as Programmable Peripheral Interface. It has 24 I/O pins. The three 8 bit ports are PA, PB, PC.
In PAM, amplitude of pulses is varied in accordance with the instantaneous value of modulating signal. It is basic technique for all modulation
Logic Gates are device with two or more inputs and only one output. There are different types of gates used to obtain different logical expressions.
Superposition theorem is applicable to circuits with linear elements. They are not applicable to power since it is a non-linear quantity.
The Programmable Interrupt controller is also known as PIC micro-controller. It is used as interfacing device. It has different operating modes.
