... a readout of -20 dB on Ivolts 2 /Hz with a total bandwidth of 10,000 Hz and 400 lines in the spectrum. Each "line" is 25 Hz wide and the power is 0.01 V 2 /Hz so the ... resulting Fourier analysis and add bands in groups. If the original record was for 10 s the bandwith would be 0.1 Hz and adding 10 bands would widen the bandwidth to 1...
