Abstract: A video signal transmission system includes adaptive compansion circuitry to improve the signal-to-noise ratio of transmitted signals. A compandor (510) at the transmitter, and corresponding inverse compandor (600) at the receiver, are arranged to have a plurality of selectable compansion transfer characteristics. Selection (530, 660) of particular ones of the transfer characteristics is responsive to, e.g., predicted values (550, 570, 630, 640) of current signal.

Abstract: Apparatus for augmenting a television signal with auxiliary signal includes circuitry for modulating a picture carrier with baseband video signal to generate a vestigial sideband television signal. Auxiliary signal (54) is modulated on a further carrier (CA) of such frequency that the upper sidebands fp - (2n+1)fH/2 of the modulated further carrier, representing the auxiliary information, 1) occupy the frequency spectrum of the vestigial sideband of the vestigial sideband television signal (50) and 2) occur clustered at odd multiples of half line frequency. The sidebands of the modulated further carrier are added (52) to the vestigial sideband television signal in frequency interleaved fashion in the vestigial sideband spectral region.

Abstract: Neural nets using capacitive structures are adapted for construction in complementary metal-oxide-semiconductor integrated-circuit technology. In each neural net layer synapse input signals are applied to the inverting and non-inverting input terminals of each of a plurality of differential-input non-linear amplifiers by a respective pair of capacitors, which non-linear amplifiers generate respective axon responses. Alternatively, fully differential input amplifiers in each neural net layer apply their push-pull responses to synapse input signals via a pair of input lines. Each push-pull response is applied via a pair of capacitors of complementary capacitance values and an output line to the input of each of a plurality of non-linear output amplifiers in that neural net layer, which generate respective axon responses for that neural net layer. In certain of these neural nets, arrangements are described that make the capacitive structures bilaterally responsive, so that back-propagation calculations can be performed to alter the relative values of capacitors in each pair thereof, which is done during training of certain of the neural nets described.

Abstract: Extended definition television (EDTV) signals including a compatible composite wideband signal (SWB) and a separate helper or extended definition signal (SNB) are combined (18), for example, for recording purposes (20), using frequency multiplexing techniques. The helper signal (SNB) is applied to a modulator (16), which produces a suppressed carrier modulated signal, to frequency shift the helper signal to a spectral band above the frequency band occupied by the compatible composite wideband signal. The frequency shifted and wideband signal are then added (18) to form the combined signal.

Abstract: Electronic control circuit for use with electrical load powering apparatus having a load connection (OA), a high voltage supply connection and a common, and with an electronic switch (13) to switch the high voltage supply connection to the load connection. The electronic switch (13) has an input (15) and is responsive to a voltage difference between the input and the load connection. The load connection (OA) is subject to high voltage excursions relative to the common due to the switching. The electronic control circuit includes a transformer (51) having a primary winding (53) and a secondary winding (55) for providing at least one pulse output from the secondary winding, the transformer having an inherent interwinding capacitance (Cw) between the primary winding and the secondary winding. A circuit connected to the secondary winding couples the pulse output from the secondary winding between the input (15) of the electronic means and the load connection (OA) when the pulse output is present. A high voltage excursion on the load connection charges the inherent interwinding capacitance (Cw) to a high voltage level when the pulse ouput is present. The electronic control circuit further includes circuitry for bypassing the high voltage level on the inherent interwinding capacitance of the transformer to the load connection when the pulse ouput and each high voltage excursion cease, including an active control circuit (75) having an input and first and second control leads and a resistive path (81, 89) substantially free of inductance between the input (83) of the active control circuit and the input (15) of the electronic switch. The active control circuit thereby bypasses current from the input (15) of the electronic switch to the load connection (OA) through the first and second control leads and the high voltage level is prevented from actuating the electronic switch when each high voltage excursion ceases. An electronically commutated motor system, a switching regulator power supply and methods of operation are also disclosed.

Abstract: Apparatus is disclosed for reducing unwanted jagged diagonal artifacts in a video signal. At an encoder, apparatus (38) intraframe averages moving image information over a given frequency range, e.g., above 1.4 MHz, while still image information is subjected to a field repeat process over a given frequency range. At a decoder, apparatus (1337) subjects still image information to a frame repeat process over the given field repeat frequency range, while moving image information is left unchanged.

Abstract: Variable length codewords are grouped into successive N bit word groups (25) in sequential order as received from a variable length codeword encoder (18). The N-bit groups are each stored in corresponding N-bit-wide memory locations in a buffer memory (30) prior to transmission over a channel (16). The locations are filled to capacity on one clock pulse and emptied on a second clock pulse to efficiently utilize the memory at a given clock rate.
