ABSTRACT:
In a parabolic signal generator, a sync pulse is applied to a saw-tooth wave generation circuit, the output of the saw-tooth wave generation circuit is entered to an absolute value circuit, the output of the absolute value circuit is entered to a logarithmic amplifier, the output of the logarithmic amplifier is entered to a linear amplifier, and the output of the linear amplifier is entered to an antilogarithmic amplifier. The absolute value circuit, logarithmic amplifier, linear amplifier and antilogarithmic amplifier are powered by a single-voltage power source, and these circuit and appliers have reference input terminals supplied with a common bias voltage.
