Engineering

There are three operational amplifiers in the circuit of an Instrumentation Amplifier of which two non inverting amplifiers are the inputs.

Crystal Oscillator is specially designed in a circuit to provide low impedance when it operates in series-resonant mode and high impedance.

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.

As proposed by Hendrik W. Bode a Bode Plot is simply a graphical representation used to design and analyze any control system.

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
