Any other informations we should know?this project will be a full-analog one.
How?By the way, what about multiplying PWM signal? Does it lead to anywhere?
For instance, using a 2.5Hz cutoff frequency RC filter would be OK, but if the source is at 500Hz, change of output will be slow, in hundreds of milliseconds range.
How should this be possible with 5 or 50 Hz pwm frequency? An optimal processing scheme would need minimum 1 pwm period to measure the duty cycle. Any analog circuit utilising filters needs additional filter settling time.Settling time should be less than 5ms in any PWM input.
I wonder what's the idea behind this restriction. Because it makes the system more complex, non flexible and it makes it difficult to react on input signal failure.this project will be a full-analog one
Did you miss that I mentioned "analog divider" in post#6 already?What you mean by 'analog divider'?
