Radio communication transceiver is a radio transmitter at the same time the plane doubles as a radio receiver used for communication purposes. It consists of the transmitter and the receiver are assembled in an integrated way. In mulamula generation, the transmitter or receiver or transmitter and receiver sections are assembled separately and is part of a stand sendirisendiri and can work well sendirisendiri Currently employed both parts are integrated in turn. Aircraft simple transmitter consists of an oscillator generating radio vibration and this vibration after vibration boarded with our voice, in a technique called dimodulir radio, then by the antenna is converted into radio waves and transmitted. As we know that the sound waves we can not reach long distances, although its power is quite large, while the radio waves with a relatively small force can reach a distance of thousands of kilometers. In order for our voice can reach a far distance, then our voice superimposed on radio w...

This circuit is a five-band graphic equalizer mono, covering the audio frequency of 55Hz, 270Hz, 1kHz, 3.5 kHz and 12kHz. The basic difference between this graphic equalizer with other circuits, is instead of CI it uses transistors, the power supply is also special is +24 V 0-24v DC, this ensures low distortion and greater margins overload.   Simple 5 Band Graphic Equalizer Circuit Diagram List of components R1-4-37 = 330Kohms R2-7 = 2.2Kohms R3 = 120Kohms R5-6 = 6.8Kohms R8 to 12 = 1.8KOHMS R13 to 15 = 200Kohms R16 = 180Kohms R17 = 150Kohms R18 = 1.5KOHMS R19 to 22 = 1Kohms R23 to 27 = 220Kohms R28 to 32 = 15Kohms R33 = 10Kohms R34 = 15Mohm R35-38 = 220 ohms 1W R36 = 100 ohms C1-3 = 40V 1uF C2 = 68PF 100V C4 = 220uF 63V C5 = 1uF 100V C6 = 220nF 100V C7 = 47nF 100V C8 = 15NF 100V C9 = 5.6nF 100V C10 = 47nF 100V C11 = 15NF 100V C12 = 4.7nF 100V C13 = 1.5nF 100V C14 = 470pF 100V C15 = 68PF 100V C16-19 = 100nF 100V C17-20 = 470uF 40V C18 = 4.7uF 63V RV1 until RV5 = 50Kohms Lin.

The equalizer presented in this article is suitable for use with hi-fi installations, public-address systems. mixers and electronic musical instruments. The relay contacts at the inputs and outputs, in conjunction with S2, enable the desired channel to be selected. The input may be linked directly to the output, if wanted. The input impedance and amplification of the equalizer are set with S1 and S3. The audio frequency spectrum of 31 Hz to 16 kHz is divided into ten bands. Ten bands require ten filters, of which nine are passive and one active. The passive filters are identical in design and differ only in the value of the relevant inductors and capacitors. The requisite characteristics of the filters are achieved by series and parallel networks. The filter for the lowest frequency band is an active one to avoid a very large value of inductance. It is based in a traditional manner on op amp A1. The inductors used in the passive filters are readily available small chokes. The filter ba...
