your workbook, record the peak-to-peak amplitude of the noise output at tp73 and for con parison, copy your previous results from the other detectors. Note: The measured noise output should be significantly less than was found with the Foster-Seeley Detector(oy a factor of about five) If this was not the case, it is likely that the center frequency of the incoming FM signal is not the same as the resonant frequency of the Ratio Detector's tuned circuit. To overcome this problem, adjust transformer T2 in the Varactor Modulator block and transformer T6 in the Foster SeeleylRatio Detector block in accordance with the instructions given in Appendix Adjustment of Tuned Circuit we have seen, to reduce the problems due tn uso de even further is to pas signal dug ugh an Amplitude Limiter eineniu placed before detector that the bnrit si talio the Ratio Detector has i constau amplifi
