Abstract

Nowadays, in sophisticated technology era the wireless application is important to our life. The wireless microphone system is one of wireless system that will be discussed here. The wireless microphone system is used in motorized wheelchair system. The user will be able to move the wheelchair by using this wireless microphone as an intercession to voice recognition motor. This system has two main parts which are the transmitter and the receiver. When the sensor detects a voice, the transmitter will be triggered and begin to send wireless signal. The transmitter handles the conversion of the audio signal into a radio signal and broadcasts it through an antenna. The task of the receiver is to pick up the radio signal broadcasted by the transmitter and change it back into an audio signal. The input signal from receiver will be produced through the speaker. Therefore, the voice input must be synchronized and reflected through the speaker output. This system can be implemented in various field such as voice activated system so that user can send command wirelessly.
