Title: Optical switch
Inventor: DAVIES DAVID ARTHUR OWEN
IPC: H04Q3/52
Filed: 1996-05-20
Abstract: Optical signals used for telecommunications in time division multiplexed format are processed to remove channels for local demodulation and to replace the removed channels with locally modulated data. The received signals (15) are subjected to a further wavelength modulation (13) so that signals in selected channels are given distinctive wavelengths. After wavelength modulation the time division multiplexed signals are separated using wavelength sensitive splitters (21, 24) and the various channels are sent their correct destinations by wavelength selection. In a preferred embodiment one channel is selected and given a distinctive wavelength and all the non-selected channels retain their original wavelength. The channels with the original wavelength are provided to an output terminal (25) for onward transmission whereas the selected channel is provided (26) for local demodulation. The invention is particularly suitable for use with signals within a bit interleaved version of a time division multiplex.

Patent CA-2211094-A1 (CA)
Title: Filter with feed-forward agc
Inventor: OESTMAN THOMAS
IPC: H03G3/20
Filed: 1996-01-30
Abstract: A device and method are provided for fully realizing the precision gained internally from a conventional digital signal processor (30) by generating a feed-forward automatic gain control (AGC) signal. The feed-forward AGC bit is indicative of the output of the digital signal processor being multiplied by a gain factor when the output from the digital filter (31, 32) included in the digital signal processor is below a threshold value. When the feed-forward AGC signal is received by an inphase and quadrature (I/Q)-to--(logR/.phi. ) converter (50) connected to the digital signal processor, a corresponding value is subtracted from the radius component of the signal calculated by the (I/Q)-to--(logR/.phi. ) converter. Because conventional digital signal processors have 16 IO bits, the feed-forward AGC signal allows an input signal with a dynamic range and precision exceeding 16 bits to be transferred from the digital signal processor without loosing performance. As a result, a digital signal processor with a fewer number of 10 bits than is nominally required for the precision and dynamic range of the output signal is implemented.
