Abstract
The adaptive loop gain phase filter of the invention utilizes an averaged value of the phase error at each baud time instead of the phase error for generating the value of the frequency shift. Such an averaged value is obtained by accumulating in accumulator ACCU2 (34) the phase error at each baud time after multiplying it by a factor K.sub.O, and is provided either very M baud time when a counter (38) preset at M reaches O, or if the contents of accumulator (34) reach a predetermined limit value. The value of the frequency shift which is accumulated in accumulator ACCU1 (14) is every accurate and enables the phase disturbance such as line breaks and phase hits to be overcome.
