IC rprecision waveform generator with sweep and frequency modulation


Posted on Feb 4, 2014

These circuits are similar to that of Fig. 5-47, except that the circuits provide for FM or sweep modulation. Use circuit 5-50A for FM (small deviations, about ±10%). Use circuit 5-50B for a sweep range of 1000:1. As a guideline, the sweep frequency approaches 0 Hz when the voltage at pin 8 equals VCC, and reaches maximum at the lower pin-8 voltag

e limit of VCC - (1/3 VSUPPLY -2). Waveform symmetry variations can be minimized when a 10-M resistor is added between pins 5 and 11.
