摘要： The output from a digital signal amplitude regenerator circuit in which the amplitude of a transmitted burst data signal is amplified, and an initial potential generator circuit, are connected to a switch. While there are no burst data, the initial potential generator circuit provides a circuit for compensating for degradation in pulse width comprising a low-pass filter, a pulse width compensation threshold generator circuit, and a limiting amplifier, with an initial potential needed to set a threshold. When a carrier detection signal generator circuit detects the arrival of a burst data signal, a carrier detection signal is outputted, and the switch is switched over from the initial potential to the burst data signal. Thus, the circuit for compensating for the degradation in pulse width located at a later stage can detect a threshold from an optimal initial potential, and thereby the degradation in pulse width can be optimally compensated.
