Abstract

PURPOSE:To obtain a miniature and economical distortion correction circuit of low power consumption by providing a reference pulse generating circuit which compares an input with the reference and selects one for a longer make time. CONSTITUTION:When a distorted dial pulse for less than a fixed make time is applied to the input terminal, reference pulse generating circuit 1 composed of a monostable multivibrator, etc., operates to generate a pulse for the fixed make time. This output and the input dial pulse are compared by OR gate 2 to output longer- make-time one. In case of a distorted dial pulse for the fixed make time or longer, it operates in the same way and if the make time is longer than the prescribed one, the input is outputted as it is. This distortion correction circuit can be miniaturized through electronic implementation and economic because of low power consumption, and it can also be adapted to systems of 10pps and 20pps in dial speed.
