Timing signal generator

A timing signal generator comprising:

• means for demodulating an input modulated signal into first and second baseband signals having a quadrature relation with each other;
• means for converting the first and second baseband signals into angle data representing a phase;
• means for calculating a difference between the phase represented by the current angle data and the phase represented by the previous angle data which precedes the current angle data by a 1-symbol interval, and outputting data representative of the calculated phase difference;
• means for determining which of predetermined divided regions contains a point corresponding to the calculated difference data;
• means for converting the output data of the calculating means into a binary reference signal in response to which of the predetermined divided regions contains the point corresponding to the calculated difference data;
• and
• means for generating a symbol timing signal in synchronism with the binary reference signal.
