A multi-purpose signal generator circuit

Published:2011/11/21 1:30:00 Author:Ecco | Keyword: multi-purpose signal generator

The circuit is shown as the chart, IC1, C1 form the oscillator with frequency being 400HZ; IC2, C3 form the 37MHZ about high-frequency oscillator ; the low-frequency signal output from the C2 can make modulation for high-frequency signal. C4 and antenna constitute a launch system. High-frequency oscillator's harmonic can be used as the three channel receiver in the television(or other channel ), and it shows black and white stripe signal. Points A , B output signals , which are respectively used for the detection signal source for low-frequency channel and image. C3 can replace the quartz crystal to stabilize the oscillation frequency, and it is shown in dotted line. Frequency can be selected 465KHZ, 10.7KHZ, 6.5KHZ, 4.43MHZ, 37MHZ.   (View)
