Well foundation is deep one which generally provided for construction of bridges.World famous “Taj mahal” stands on well foundation.

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.

The entropy of a substance is a real quantity, just like pressure, volume and temperature. Its unit is joule/Kelvin (J/K).

A draft tube is a pipe of gradually increasing diameter which connects the exit of runner of a turbine to the tail race.

A crystal is a solid whose constituent atoms, ions or molecules are closely packed in a regular fashion with repeating pattern in three dimensions.
