ABSTRACT:
Constant-percent break interval pulse correctors insure that the break interval of a dial pulse subsists for a substantially constant percentage of the total pulse interval; i.e., break interval plus make interval. The constant-percent break interval pulse correction of the first pulse in a string of pulses is realized by employing an up/down counter which is controlled to count up at a first clock rate for a first predetermined interval from the beginning of the dial pulse, then to count down at a second clock rate for a second interval from the end of the first interval to the beginning of a subsequent dial pulse and then to count down at a third clock rate until a predetermined count is reached, e.g., zero. The second clock rate is the difference between the third and first clock rates. In one embodiment, proper correction of the last dial pulse in a string of dial pulses is realized by employing a plurality of such up/down counters. A first counter is triggered by the leading edge of the first dial pulse in the string. Thereafter, each of the up/down counters is triggered by the trailing edge of the prior dial pulse being corrected.
