RANCANG BANGUN RECEIVER MENGGUNAKAN MIKROFON WIRELESS DENGAN KELUARAN 4 BUAH SPEAKER

Microphone wireless is a communication medium that is often used in everyday life. Microphone with cable as an intermediary, relatively short range because it depends on the length of the cable. However, the wireless microphone transmitter and receiver uses radio waves as well as the intermediary. This final report describes how the wireless microphone receiver circuit, where the receiving antenna will receive the incoming input signal in the form of electromagnetic wave signal is then converted into electricity were. After that, the electrical signal will be amplified by the RF amplifier before entering the mixer (mixer) to increase the signal to noise ratio. In the mixer local oscillator that functions contained generate higher frequency vibrations of the RF output signal frequency. Then the signal is passed to the selection of the required frequency on the IF amplifier and filter out (filter) unwanted signals in the mixer output. After that, the electrical signal will be amplified at the AF amplifier where the signal generated is reproduced audio signal. And the incoming signal to the speakers so that the sound can be hear
