ABSTRACT:
A method and apparatus for instantaneously adjusting the threshold level for amplitude qualification in a signal peak detection system. Two threshold levels are provided, an upper threshold level and a lower threshold level. As the input signal level exceeds a first qualifying value, the amplitude threshold is set to the lower threshold level. If the input signal continues to increase and exceeds a second qualifying value higher than the first qualifying value, the amplitude threshold is set to the upper threshold level.
