Hi,
I am using a AVR microcontroller at 4MHz and have a varying frequency
(50Hz max) sine wave from an allegro current sensor, is there a low
computational algorithm to calculate a close approximation to the RMS
current for a signal like this? The signal into the allegro current
sensor is a sine wave within about +-3amps.
Well ... you could sample it and do the RMS calculation mathematically.
