For audio- frequency power measurement a rectifier type voltmeter will be used choosing proper diodes for the rectifier that offer minimum capacitance. A standard resistance of 600 ohm will be taken and the rectifier type voltmeter will be connected across it. When 1 W of power is dissipated across this resistance the voltmeter reads 0.775 V.

THE FREQEUNCIES ARE 1560 Hz, 1620 Hz, 1680 Hz, 1850 Hz THE DIFFERENEC IS ONLY 60 Hz and will require FFt with bandwidth of 20 hz or so to be able to distinguish these. One method is to multiply the signal with say 1620 hz and average it with a low pass filter . This is the same principle used in lock in amplifiers.
