Enhanced data rate receiver

A receiver having circuitry for generating first digitized samples from a received analog signal at a first sampling rate, e.g. an ADC. An interpolating filter is used to generate second digitized samples which are estimates of samples obtainable by sampling the received analog signal at a second sample rate lower than the first sampling rate, second digitized samples being output at the first sampling rate and including at least one unusable sample. A circuit is provided for generating a signal for controlling components of the receive path downstream of the interpolation filter to prevent processing of the unusable second digitized samples.
