1.1 INTRODUCTION
A wireless microphone is a microphone without any physical cable connecting. It is directed to the sound recording or amplifying equipment with which it is linked. Usually, it requires a wireless transmitter, and a wireless receiver. The transmitter either is connected by a short cable to a body pack transmitter built or is into the microphone. The wireless transmitters require a broadcast and battery through an external antenna or internal antenna. The wireless receiver is tuned to electromagnetic wavelength as same to the transmitter. It is physically attached to an output device like a closed system headset or a PA system
In communication system, students learn the basic block diagram for communication system. From the theory the student will apply to the block diagram and know the function for every single block diagram.
a) Electronic communication: Transmission, reception and processing of information between 2 or more locations using electronic circuit.
b) Information : Analogue or digital signal that had been converted to electromagnetic energy
c) Transmitter: Collection of one or more electronic devices or circuits that convert the original source into a signal that is more suitable for transmission over a given transmission medium.
d) Receiver: Collection of electronic devices and circuits that accepts the transmitted signal from the transmission medium and converts them back to their original form.
e) Transmission impairments: Any undesired effect on the signals while travelling from the transmitter to the receiver, such as noise, attenuation, interference and other losses caused by the atmosphere or the medium itself.
1.2 PROBLEM STATEMENT
Nowadays, the trend of communication is toward the wireless where there are no more knotty wires that limit your distance and movement. So, we are required to produced a wireless microphone and its receiver.
i. Wiring microphone not gives freedom or movement for the speaker.
ii. Wiring microphone have cabling problems, caused by constant moving and stressing the cables.
1.3 OBJECTIVES
The purposes of this project are:
i. Design the wireless microphone to overcome the problem.
ii. To make us understand about how wireless microphone function and setting specification of frequency range to operate.
iii. To make a research about operation of transmitter and receiver
iv. To understand how to design the circuit
v. To understand the spectrum frequency by experiment
vi. To understand more learning in Communication Engineering
METHODOLOGY
2.1 INTRODUCTION
A methodology is instantiated and materialized by a set of methods, techniques and tools. A tool is any instrument or apparatus that is necessary to the performance of some task. A methodology does not describe specific methods, nevertheless it does specify several processes that need to be followed. These processes constitute a generic framework. They may be broken down in sub-processes, they may be combined, or their sequence may change.
Methodology may be a description of process, or may be expanded to include a philosophically coherent collection of theories, concepts or ideas as they relate to a particular discipline or field of inquiry.
The flow chart in this project can be simplified as follow:
