When to Use a Quadrature Decoder A quadrature decoder is used to decode the output of a quadrature encoder. A quadrature encoder senses the current position, velocity, and direction of an object (for example, m
A signal processor converts quadrature phase signals, from an encoder, representative of a measured parameter, into data which is directly readable by a computer and representative of the magnitude and direction of the current value of the parameter. The signal processor decodes binary signals repres...

Because the second portions of the first and second amplitude limited differential pulse trains are out of phase with one another but of similar frequencies, the exclusive-or-logic gate of phase determining circuit 460 generates a periodic signal on lines 462 and 464 that is twice the frequency ...

In effect, by transfering the complexity of signal processing to the encoder side of the signal distribution system (i.e. television studio) the present invention enables the use of very simple decoders in low-cost receivers to achieve superior pictures without unwanted dots or cross-color pattern...

It would be desirable to have receiver structures that involve trellis decoders to decode the SSB-processed modem signals. It would be desirable to have trellis coded modulation schemes to improve minimum path distance in the trellis encoders. It would be desirable to integrate such receiver struct...
