      peak detector
    Several pieces of different musical kinds were studied measuring A(t), the output amplitude of a peak detector driven by the electric signal arriving to the loudspeaker.
          
    It will be shown that a simple model, only consisting of a linear filter followed by a noisy peak detector, suffices for a fair quantitative description of the available data.
          
    A theory is developed by which the trigger jitter can be predicted from the properties of signal and noise for a system consisting of a filter and a single-level, dual-level or peak detector.
          
    Using this theory the trigger jitter of a given filter-level detection system is compared with that of an optimal detection system consisting of a matched filter and peak detector.
          
    This resulted in an average trigger jitter of 0·2±0·1 ms for the optimal system, while for the peak detector and the dual level detector the jitter was slightly higher provided that the QRS complexes were symmetrical after filtering.

      envelope detector
    A replica envelope detector provides a reference DC level, producing a pseudo-differential baseband output.
          
    An envelope detector detects the amplitude of the signal and controls the DC-DC converter output.
          
    It is obvious that a simple counter after the envelope detector can act as the decoder, which makes the logic circuitry design much easier.
          
    Simulation of AM/FM demodulators using filter and envelope detector blocks.
          
    This type of envelope detector can be used with a wide range of carrier frequencies.
