Filed: 2000-03-29
Abstract: PROBLEM TO BE SOLVED: To provide a synchronous circuit with a simple circuit configuration, without deteriorating the synchronization detection performance that realizes a cost of a receiver, reduction in the power consumption and improvement of a processing speed. SOLUTION: A 1st counter section 74' counts number of clocks when an output signal of a 1st comparator 73' is positive and resets the count when negative. Furthermore, an arithmetic section 75' subtracts the count received from the 1st counter section 74' from a number doubling a sample number of a guard period. A 2nd comparator section 76' outputs a positive signal when an output (n) of the 1st count section 74' is a predetermined value (X) or over. In this case, the value (x) is selected sufficiently higher than the output other than a correlation value of the guard period counted by the 1st count section 74' so as to prevent the positive signal from being outputted in wrong timing.  A 2nd count section 77' keeps an output of the arithmetic section 75' to start counting number of clocks when a correlation input signal c2 takes a positive value for a long time and then takes a negative value and outputs a positive signal as shown in Figure 2(f) when the count is equal to an output value of the arithmetic section 75'.
