摘要： A blending function generator for use in the electronic commutation of a ring of antenna elements in doppler omni-range (DVOR) systems. The blending function comprises a first lobe flanked by second and third lobes, the first lobe consisting of a cosine lobe having a period of 2T seconds where T Ymn where m is a number and n is a whole number, the second and third lobes each consisting of a cosine lobe having a period of T seconds, the second and third lobes being of the same phase and of opposite phase to the first lobe.

摘要： A phase measuring and monitoring circuit adapted to measure the phase difference between a reference signal and a monitored signal having a counter switchable to either an add or substract mode, the input to which is a sequence of measured pulses controlled by a filter and zero-crossing detector, the inputs of which are time-shared by the reference signal and the signal to be measured.
