observe the audio modulating signal at tpl4(trigger on this signal) and the output from the Foster Seeley at tp52 A considerable amount of ripple' at frequency of the noise input may also be seen Reduce the Amplitude preset in the Audio Oscillator to minimum(fully counter-clockwise). This will ensure that no frequency modulation will take place Ensure that the Gain presets in the Mixer Amplifier and Low Pass Filter Amplifier Gain blocks are both set to maximum(fully clockwise). Use your oscilloscope to monitor the signal at tp73 at the output of the Low Pass Filter Amplifier block and the"noise signal at tp5(Trigger the oscilloscope from tp5.) The signal from tp73 is now only the noise output resulting from the amplitude vanations occurring at the input or the Foster- Seeley Detector yout workbook record the peak-to-peak amplitude ofte noise outpur at In Ip7 sad fot compariso copy your previous results from the other detectorsc
