Simple Stereo VU Meter

This project will indicate the volume level of the audio going to your speakers by lighting up LEDS. The LEDS can be any color so mix them up and really make it look good. The input of the circuit is connected to the speaker output of your audio amplifier. You want to build two identical units to indicate both right and left channels. The input signal level is adjusted by the 10k ohm VR. If you wish to make a very large scale model of this unit and hang it on your wall there is an optional output transistor that can drive many LEDS at once. The unit I built drove three LEDS for each output. The sequence of the LEDS lighting are as follows Pin 1, 18, 17, 16, 15, 14, 13, 12, 11, 10. visit page. via next.gr

Stereo TV Decoder Circuit

A simple stereo tv decoder circuit build with MC1310P. Transistor Q1 is an audio amplifier and U1 is used as a 31. 5KHz subcarrier which is similar to 38KHz FM MPX. Pilot frequency is 15. 734KHz. No, it cannot be used with the to decode the stereo signal. Radio stereo signal has a different frequency. The MC1310P is used in the SAE 3200 Stereo FM visit page. tuner. There are newer and better IC`s today. LM4500 Bob in the FM Tuner group makes a kit with PC board for this one.

Am Radio / Fm If Stereo System Ic

The BA3822LS BA3822FS BA3823LS and BA3824LS are monolithic, five-point stereo graphic equalizer ICs. Each IC has two channels, and the five center frequencies for each channel are independently set using external capaci- tors. These ICs feature a wide operating power supply voltage range (VCC = 3. 5V to 14V), and are available in compact 24-pin SZI visit page. P and SSOP packages, depending on the type. This makes them an ideal choice for home stereo systems, Radio cassette players, and car stereos. The difference between the ICs is the amount of boost and cut control.

FM stereo transmitter

This stereo FM stereo modulator circuit use the BH1417F FM stereo transmitter IC which consists of a stereo modulator for generating stereo composite signals and a FM transmitter for broadcasting a FM signal on the air. The stereo modulator generates a composite signal which consists of the MAIN, SUB, and pilot signal from a 38kHz oscillator. This visit page.

BH1417F stereo FM transmitter is capable of broadcasting good quality signals over a range of about 20 meters and is ideal for broadcasting music from a CD player or from any other signal source so that it can be picked up in another location. L1 coil comprises 2. 5 turns of 0. 5 - 1mm enamelled copper wire (ECW) wound onto a tapped coil former fitted with an F29 ferrite slug. Alternatively, you may also use any commercially made 2. 5 turns variable coil.

Stereo modulator circuit design electronic project

Using BA1404 can be designed a very simple and useful fm stereo modulator electronic project. This BA1404 fm stereo modulator device works in FM broadcast band ( 75- 108MHz) and require few external common components. The BA1404 fm stereo modulator Ic contains all parts needed to design an simple high efficiency stereo transmitter circuit. This visit page.IC contains a stereo modulator that creates stereo composites signals, an FM modulator that creates FM signals and a RF amplifier. The fm stereo transmitter develops composite signals made up of a main(L+R) signal and sub(L-R) signal and a pilot (19KHz) signal using a 38KHz crystal oscillators. via next.gr
