TRI-LEVEL SANDCASTLE PULSE DECODER

摘要

RCA 76,343 Trilevel sandcastle pulse decoder includes a trio of voltage comparison means for comparing incoming sandcastle pulses with reference potentials of respectively different levels. One of the voltage comparison means, which is subject to change in operating state in response to appearance of a given level of the sandcastle pulse, is precluded from operating state change in response to the appearance of the next higher level of the sandcastle pulse by control circuitry responsive to the output of a second of the voltage comparison means. One of the decoder outputs is developed by logic circuitry responsive to outputs of two of the comparison means.
