Abstract: RCA 73,365 ABSTRACT OF THE DISCLOSURE           In television image size altering apparatus of the type wherein pixels relating to a composite video signal are sampled at a synchronous real time rate and wherein the flow of pixel information is coordinated through a memory by a write control and a read control, the composite pixel information is separated into original pixels relating to each basic component of the video signal.  Interpolated pixel values are then derived from the original pixel values at an effective rate less than the synchronous rate when compressing the image size and at an effective rate greater than the synchronous rate when expanding the image size. The interpolated pixel values are then combined into new pixel values relating to a new composite video signal and the new pixel values are presented for display at the synchronous rate to alter the size of the television image.

The display may be in cartesian format having mX electrodes and nY electrodes in which case the X electrodes are in strip form whilst each Y electrode comprises two or more interleaved components Ya, Yb.   Thus each XY intersection may be addressed by a zero voltage at XYa, or XYb, with above threshold voltages elsewhere.   A series of m different coded waveforms are generated and applied a different one to each X electrode.   The two traces are sampled and converted to digital sample values.   Coded waveforms are generated and applied to each YaYb electrode contemporaneously with those applied to the X electrodes;  the codes being generated are selected from the m different codes and relate to the position of the Y electrode and the sample value to be displayed. The coded waveforms may be binary codes such as pseudo random codes. priority encoder allocates a priority to sample values of the two trace signals.

Abstract: ABSTRACT:          "Digital echo canceller".     An echo canceller is used to cancel an echo signal occurring in the receive path of a data trans-mission modem in response  to the signal appearing in  the transmit path. This echo canceller comprises a controlla-ble digital filter connected to the transmit path and adjusted by means of a control circuit, a difference circuit producing a residual signal resulting from the difference between the signal in the receive path and the synthetic echo signal supplied by the filter and an analog-to-digital converter which converts the residual signal into a digital control signal for the control circuit. In order to have the echo canceller function in a homo-chronous transmission system with an analog-to-dlgital converter having a reduced number of bits, said converter has a controllable dynamic which is adjusted by the output signal of an attenuation circuit connected to the output of a circuit which detects the peak value of  the residual signal t
