摘要： PROBLEM TO BE SOLVED: To provide a signal detection circuit and an incorrect detection preventing method which prevent incorrect detection caused by noise having periodicity. SOLUTION: The signal detection circuit has a sampling portion (101) which samples an external signal according to a sampling frequency signal, a noise period measurement portion (104a) which measures the period of a periodic noise from a sampling result, an external signal determination portion (103) which determines the level of the external signal from the sampling result, and a control portion (104b) which sets the sampling frequency signal to a predetermined frequency which is capable of detecting noise when in the noise period measurement, transfers the sampling result "a" at that time to the noise period measuring portion, after measuring the noise period, sets the sampling frequency to a frequency not identical with the frequency relevant to the measured noise period, and controls so that the sampling result "b" at that time is transferred to the external signal determination portion 103.

摘要： PROBLEM TO BE SOLVED: To provide a configuration of holding a count of a counter with a smaller circuit scale when the count of the counter reaches an expected value. SOLUTION: When the count of the counter 1 reaches the expected value (n) and a decoder 4 outputs a decode signal, a logic circuit comprising a NOT gate 11, a NAND gate 12 and a NOT gate 13 outputs an OR signal between the decode signal and a clock signal to a clock input terminal of the counter 1 to block the clock signal from being outputted to a D flip-flop 2 being a component of the counter 1.

摘要： PROBLEM TO BE SOLVED: To allow the object device receiving a digital signal to easily select a noise. SOLUTION: A comparator 1 receives a signal and applies binary processing thereto and gives a digital signal resulting from the binary processing to an input terminal of a timer 2 and of an OR gate 3. The timer 2 gives the digital signal at a high level to the OR gate 3 for a prescribed time when the received digital signal goes to a high level. The OR gate 3 ORs the digital signals from the comparator 1 and the timer 2 and gives a resulting digital signal to a driver 4. The driver 4 buffers the digital signal received from the OR gate 3 and gives the buffered result externally.
