Q. What is an amplifier? What are the various types of amplifiers?
AMPLIFIER: A circuit that increases the amplitude of the given input signal is an amplifier. A small a.c. signal fed to the amplifier is obtained as a larger a.c. signal of the same frequency at the output. They constitute the essential parts of many communication circuits such as television and radio.
Q. Show Balanced three-phase loads? Three-phase loads can be connected in either wye (also known as star or Y) or delta (otherwise known as mesh or ). If the load impedances i
Q. What do you mean by Companding? Companding is the process of compressing and expanding. It comprises compressing the signal at the transmitter and expanding it at the receiv
