Design And Construction Of A Wireless Microphone

ABSTRACT

In the communication industry today, the importance of microphones cannot be over emphasized. They can be found in different shapes and sizes as well as single units for public address systems, or are built into devices such as telephones, tape recorders etc. The basic microphone usually consists of a handheid unit (microphone) with a cable connected to it. [1]. This hand held unit is used to convert audio signals into electrical signals, which are then transmitted through the cable and terminates at an amplifier, a recorder, a phone etc.[2] A wireless microphone as the name implies is a microphone without a physical cable connecting it directly to the sound recording or drilplitying equipment with which it is associated [3], [2].
