Abstract
A receiver which receives a signal transmitted while the symbol rate is changed over from among a plurality of different values, and which varies, in accordance with the symbol rate, the pass band width of the filter that removes unwanted signals from the detector output. By compensating for changes in delay produced by alteration of the pass band width of the filter, a receiver, according to this invention, recovers a clock that is synchronized with the symbol rate after changeover, without discontinuities occurring when the symbol rate is changed over.
