RMS (root mean square) function
RMS is computed from one of the module’s 4 analog input channels according to the
formulaL
Where f(x) denotes the input channel signal and T the time window (in ms).
Keep in mind the following notes when working with RMS channels:
S The maximum sample rate is restricted to 4800 (2400) Hz
S The output (sample) rate of the RMS channel must not be higher than the sample rate of
the input channel
S Filters set for the MX410 do not apply to RMS channels. These channels are always
unfiltered. However, the input signal is filtered
