Timers Generate Variable-Sweep Frequencies -  08/01/96 EDN Design Ideas:  The circuit inFigure 1 generates a 4- to 5-kHz output frequency that precisely sweeps a variable amount of 1 to 100 Hz over a variable time of 0.5 to 5.0 sec (1000-to-1 rate range).  The resolution is 1 Hz, and worst-case accuracy during the sweep is 3 Hz (0.06%).  This circuit was designed to run from an 8-bit PC iSA bus, but any C with an 8-bit bus and the appropriate control signals can control the circuit. Design by D Hayden, Hayden Electronics Design, San Diego, CA
