Abstract
A peak detector comprises a device for storing a value representing the currently detected peak amplitude (C,,C,), a circuit for detecting whether the input signal amplitude exceeds the stored value (D1 to D4), an apparatus for updating the stored value at a fast rate if the input signal amplitude exceeds the stored value by more than a given value (D1/V1, D3/V4), and an apparatus for updating the stored value at a slow rate if the input signal amplitude exceeds the stored value by less than the given value (D2/R2, D3/R3). Analogue and digital versions are described together with their application to data slicers in, for example, teletext decoders.
