Filed: 1975-02-14
Abstract: 1466213 Counting apparatus BENDIX CORP 14 Feb 1975 [14 March 1974] 6416/75 Heading G4A [Also in Division H3] The invention relates to apparatus for calculating the reciprocal of a period between recurring events mainly for the purpose of measuring velocity by generating a signal of frequency proportional to velocity, measuring the period of the signal and then calculating the reciprocal of the period as a measure of the velocity. The invention seeks to reduce errors due to noise in the high frequency signals produced by high velocities by calculating the reciprocal over several periods at high velocity while calculating it for a single period at low velocities. A first pulse of the signal resets counters 14, 18. Counter 14 counts clock pulses to a predetermined count and then releases an enable signal to start a digital differential analyser 20 which starts to generate a signal 30 corresponding to the reciprocal of the period. Meanwhile counter 18 counts the number of signal pulses. At the first signal pulse after the end of the predetermined count the output of DDA 20 is sampled and its instantaneous value is multiplied at 22 by the number of signal pulses, to arrive at a value of the velocity. The DDA 20 (Fig. 3, not shown) employs a plurality of circulating shift registers to generate the digital representation of the reciprocal curve 30.
