Modification of a Semi-Precision Range-Delay Circuit for Operation at High Duty Cycles
Abstract
In one of the best basic semi-precision range-delay circuits using an accurately compensated sawtooth generator as a time base, operation of a unit designed for a 100,000-yard maximum delay was limited to duty cycles below 50% at the usually desired accuracy of 0.1% -- a serious limitation particularly at long ranges. Modification was undertaken to extend unsatisfactory operation to duty cycles of up to 80%, almost the limit of stable operation for readily available components outside the sawtooth generator.
