IPC: H03H21/00
Filed: 1992-09-28
Abstract: A tap-weight controller (5) of a matched filter includes a tapped delay line having a series of delay elements (22-26) for receiving an incoming digital signal to produce successively delayed signals at successive taps of the delay line so that the signal at the center tap coincides with the output of a decision feedback equalizer (DFE 7). Correlation circuits (27-1²27-5) are provided corresponding respectively to tap-weight multipliers (16²20) of a transversal filter (4) and to the taps of the delay line of the tap-weight controller. In each correlation circuit (27), correlation is detected between the output of the DFE and a signal from the corresponding tap of the delay line, and a signal indicating the detected correlation is integrated over a prescribed interval (32). An adder (35) has a first input for receiving the detected correlation signal and a second input for receiving the integrated signal or a tap-weight control signal to produce a summed signal. The correlation signal is delayed by a shift register (37) for the prescribed interval and subtracted by a subtractor (36) from the summed signal to produce an output which is applied to the adder as the tap weight control signal as well as to the corresponding tap-weight multiplier (16²20). The integrated signal is initially applied to the second input of the adder, and thereafter, the tap-weight control signal is applied to it to update the control signal at symbol intervals.

Abstract: A time-division duplex radio transceiver is disclosed which can avoid the deterioration of reception sensitivity and interferences in other radio communication equipments of the same kind which may be caused in the conventional transceiver by generation of an interfering signal of a transmission frequency or a frequency in the vicinity thereof in the transceiver even upon reception. In the time-division duplex radio transceiver according to the present invention, in order to generate a carrier frequency signal in the transmission state or an intermediate frequency in a transceiver portion, there are provided an oscillator (18; 54) for making oscillation at a frequency higher than the carrier frequency and the intermediate frequency and frequency dividers (20, 21; 56, 57) for frequency-dividing an output of the oscillator, and the operation of the frequency dividers is stopped in the reception state. Accordingly, while the oscillation of the oscillator is always continued, it is possible to prevent the transmission frequency or the frequency from being generated in the vicinity thereof in the transceiver in the reception state.

Abstract: An apparatus for generating a high speed dubbing signal to be recorded by an external recording apparatus. The high speed dubbing signal whose pitch is N times a digital input signal is generated as follows. An encoding circuit (113) subsamples the digital input signal consisting of frame signals each of which consists of N field signals, so that each frame signal is compressed by a factor of N to be contained in one field interval. A digital signal recording and reproducing circuit (116) including a recording and reproduction system, records on a tape, at a normal tape speed and at a normal head drum rotational frequency, the compressed signal in such a manner that each field including the compressed signal appears once per frame interval, and then selectively reproduces from the tape the field including the compressed signal at the tape speed N times the normal speed and at the normal drum speed. A decoding circuit (120) interpolates the output signal of the recording and reproducing portion (116) to recover the lost information by the subsampling. An output portion produces the high speed dubbing signal based on the output of the decoding circuit (120). Since the drum rotational frequency is maintained at the normal value throughout the recording and reproduction by the recording and reproduction system, the contact between the tape and head of the system is stabilized, thereby enabling a reliable high speed dubbing.

Abstract: The invention relates to a process for the preparation of polyorganosiloxanes having a viscosity of from 0.2 to 10,000 Pa.s (at 20 DEG C) by reaction, preferably by condensation, of low-molecular-weight polyorganosiloxanols with one another or with oligomeric siloxanes in the presence of a known catalyst system. These products are silicone oils and silicone rubber polymers or starting materials for further modifications. According to the invention, the process for the preparation of polyorganosiloxanes is carried out by reacting oligomeric siloxanols having a linear or crosslinked structure (obtained by hydrolysis of organochlorosilanes), preferably linear, low-molecular-weight polyorganosiloxanols, with one another or with oligomeric siloxanes in the presence of a catalyst system known for this reaction at temperatures between 80 and 200 DEG C and at pressures of from 1 to 1000 mbar (abs.) in a thin-film evaporator. Advantages are reduced recycling due to milder reaction conditions and the reduction in the amount of intermediate fractions produced on product changeover.

Abstract: An automatic scan tracking helically scanning data recorder in which data is written on to magnetic recording tape along with data retrieval information by means of a rotating scanner assembly (24) forming part of the recorder as the recording tape (26) moves at a given recording speed in co-operative engagement with the scanner assembly. Data is normally retrieved from the recording tape along with the data retrieval information by means of the rotating scanner assembly as the recording tape moves longitudinally at the same given recording speed. In operation, the rotating scanner assembly of the recorder retrieves data and data retrieval information from a segment of the recording tape while the latter is not moving, that is, during a period when the tape is stationary for enabling adjustment of the read head position relative to the track depending on the evaluation of the data resulting from the stationary tape read. Provision is also made for causing the rotating scanner to retrieve data retrieval information from a segment of the recording tape while the latter is accelerating from a still state to its given recording state, with subsequent evaluation of the data and adjustment based on the results.
