Hi All,

I'm looking to monitor a number(~10) of slowly varying low frequency
outputs(100Hz-5KHz), I want to be able to sample & report the
frequency on each channel once every 100mS. The micro processor I'm
using has a number of ADC channels so I was hoping to use these to
monitor the output of a Frequency to Voltage converter for each
channel. The required range is 0-5V on the output of the converter.

I don't think I can use the micro to time the inputs directly because
I may not have the overhead avalable to do this every 100mS for every channel.

Why not?
I am sampling at 1 ms (with hardware timer) using a $5 micro?
A decent micro should easily meet your requirements.
