A differential multitone signal at 400, 1160, and 3200 Hz is applied to the input of an instrumentation amplifi er. Each of the tones is set to a level of 100 mV RMS, differential. The output of the circuit is measured and found to be 200 mV RMS, 400 mV RMS and 410 mV RMS at 400, 1160 and 3200 Hz, respectively. The input are shorted to a DC midsupply voltage and a single-ended multitone is added to the power supply. The input signal level is again 100 mV RMS, single ended. The output of the channel is again digitized, resulting in the following differential RMS output levels: 400 Hz: 0.01 mV RMS, 1160 Hz: 0.1 mV RMS, 3200 Hz: 0.13 mV RMS. Calculate the PSR and PSRR at each frequency
