Abstract

PURPOSE:To make it possible to execute the multiplication or division of an analog system, by combining a saw tooth wave generating circuit with a mean value circuit. CONSTITUTION:Electric charge of the capacitor 301 is discharged at the rise of a signal applied to the timing control terminal 30, and when the reset circuit 300 for setting its terminal voltage to zero is not a reset state, a current flowing into the capacitor 301 is Y', and therefore the terminal voltage of the capacitor 301, that is to say, voltage of the output terminal 32 rises up with an inclination of Y'/C. In this case, C shows the capacity of the capacitor 301. The output Z of the mean value circuit 4 becomes Z=Y'/2KC. Also, since Y'=Y, Z=Y/2KC holds good after all, and it proves to have been multiplied and divided. The mean value circuit 4 can be formed by use of the low pass filter consisting of a resistor and a capacitor only, or the active filter for which an operation amplifier is used, etc.
