#90940 - What methods have you considered? Responding to: ???'s previous message |
From your specs you want 1hz resolution from 20KHz to 50KHz - what pwm resolution do you want? Having varying frequency and pwm is a bit more challenging than fixed freq or pwm. What methods have you considered? It might just be easier done in analog! The requirement of 1hz resolution makes the solution harder - is this an absolute requirement? What you've asked for is not trivial and probably not something many of us have been required to solve. I'm sure if you sit down and start crunching some numbers you'll start to realise the difficulty in the solution. If you come up with some suggestions, I'm sure our combined experience will help you avoid common problems, but you have to do some of the work yourself - this isn't freeelcectronicengineers.com or solutionsrus.com |
