Abstract : A method of transmitting extreme point samples of an analog waveform is described in the patent in which the signal is processed in intervals of a fixed number of bits. During each interval a heading is transmitted indicating in which of the plurality of frames within the interval the extreme points lie. The remainder of the interval comprises the extreme point data plus a variable number of fill-bits. The extreme point data comprises amplitude and fine timing data. The number of encoding levels of the extreme point data decreases as the number of extreme points within the interval increases.
