ABSTRACT:
A decoder for Manchester encoded data signals in which the encoded data signals are applied to a first circuit which produces a primary pulse at each voltage transition of the applied signals. The primary pulse enables a delay line oscillator which after a predetermined period of delay produces a decode clock signal of a given frequency. The inverted primary pulse, the decode clock signal, and a constant voltage data input signal are applied to a decoder shift register. The primary pulse and selected outputs of the decoder shift register are applied to a logic circuit which produces a receive clock signal having desired low-to-high voltage transitions occurring substantially in the center of each half-bit cell of a Manchester bit cell. The receive clock signal can be applied to a receive data shift register to which the encoded data signals are also applied so that the binary value of each half-bit cell of a Manchester bit cell can be stored in the data shift register.
