Abstract

PURPOSE:To obtain the output surely rejecting noise and distortion, even if input signal is greater, by automatically changing the reference voltage of comparator depending of the input signal level and obtaining optimum value. CONSTITUTION:The input signal at the terminal 1 reaches one end of the comparator circuit 7 via the middle point 2c of the first voltage division circuit 2 consisting of resistors 2a and 2b and via the middle point 5c of the second voltage division circuit 5 consisting of the operational amplifier 3, diode 4 and resistors 5a and 5b. On the other hand, the terminal 1 is connected to the + terminal of the comparator 7. When the level of input signal is lower than the reference voltage determined with the circuit constant with input signal zero, the level is compared 7 with the reference voltage and outputted. Next, when the input signal is increased and the signal to the middle point 5c exceeds the said reference voltage, the voltage level at this point is increased, the input signal is the value divided with the first voltage division circuit, it is charged up the capacitor 6 forming the peak hold circuit, and this hold voltage and input signal are compared 7. LPF can be used in place of the first voltage division circuit 2.
