i have only really tried 400 and 12 and 25 hz same time out of it that runs the other frequencies out a touch slower line rate wise.
Three frame frequencies of 12.5, 25 and 50Hz, plus line frequencies of 200, 400, 800, 1,600 and 3,200Hz. Also 6,400 and 12,800Hz should you need them. Choosing the appropriate line and frame rates gives you quite a wide range of lines-per-frame all based on powers of two.
That sounds good thats every thing you could want i would be pleased with that !
Harry, would this be enough for what you require?
Beautiful ..Steve thats great
Klaas's Triple Waveform Generator used CD/HEF parts, what do you plan to use as the timing components may be different?
As is i think the high range would be 500hz or so ...the cap might need switching this will change the frame rate as well i hope to the ranges you mentioned above...i think the resistors can be kept as is .
