1.ABSTRACT
Hereby we are designing a detection circuit of single side band modulation or simply we can say single side band demodulator. For this we have taken two approaches to understand the SSB modulation – i) Using Matlab

ii) Building the real hardware.

3.1 BATTERY

An electrical battery is a combination of one or more electrochemical cells, used to convert stored chemical energy into electrical energy. The battery has become a common power source for many household and industrial applications.

Batteries may be used once and discarded, or recharged for years as in standby power applications. Miniature cells are used to power devices such as hearing aids and wristwatches; larger batteries provide standby power for telephone exchanges or computer data centers.

WORKING OF BATTERY:

A battery is a device that converts chemical energy directly to electrical energy. It consists of a number of voltaic cells;...
