The color killer is an electronic stage in color TV receiver sets which acts as a cutting circuit to cut off the color amplifiers when the TV receives a monochrome signal.

Both blind speeds and range ambiguities are phenomena that depend on the pulse-repetition frequency. Their effects can be reduced or eliminated by switching the pulse-repetition frequency periodically between two or more different values. This technique is called staggered PRF.

The doppler shift affects the wave incident upon the target as well as the wave reflected back to the radar, the change in frequency observed by a radar due to a target moving at relative velocity is twice that from the same target emitting a wave.

To code a signal with L number of levels, we require a coder with (log L/log 2) number of bits. So,
log 16/log 2=4 bit coder is required.

Computational complexity is one of the factor which is used in the implementation of the system. It
refers to the numbers of Arithmetic operations (Additions, multiplications and divisions).

An intrinsic (pure) semiconductor, also called an undoped semiconductor or i-type semiconductor, is a pure semiconductor without any significant dopant species present. The number of charge carriers is therefore determined by the properties of the material itself instead of the amount of impurities. Intrinsic material has equal number of holes and electrons.

A Zener diode is a silicon semiconductor device that permits current to flow in either a forward or reverse direction.
The diode consists of a special, heavily doped p-n junction, designed to conduct in the reverse direction when a certain specified voltage is reached.
The Zener diode is less expensive than another diode. This diode can be used in regulate and stabilize the voltage in a circuit. These diodes have a high-performance standard. Control the flowing current.

DC meter reads mean value.

A syntax error is an error in the syntax of a programming language which is detected by the compiler.

In two stroke petrol engine the air fuel mixture will be supplied to cylinder from crankcase via transfer port. This mixture get pressurized inside the crankcase due to the rotation of crank shaft.
