Abstract: ABSTRACT OF THE DISCLOSURE      A digital signal receiver is structured to receive and demodulate a digital signal.  Such digital signal may comprise, for example, a television signal of character multiplex transmission having the digital signal included in the vertical blanking period of the television signal and the digital signal receiver may be structured to reproduce the digital signal from the television signal.  The digital signal includes a clock run-in signal (CRI), a framing code signal (FRC) and a bit serial data signal (DA) disposed in succession.  An error of the framing code or the data signal cuased by a low frequency region group delay characteristic of a transmission path between the transmission and the demodulation is detected and, upon detection of the error, a waveform distortion of the framing code signal and the data signal is corrected by means of a correcting circuit such as an LC circuit, whereby an error of the data signal to be demodulated thereafter is prevented.

Abstract: SAMPLING SPECTRUM ANALYZER          ABSTRACT OF THE DISCLOSURE         This invention is a sampling spectrum analyzer which provides instantaneous continuous wideband spectrum analysis, thus allowing R.F. signals occurring simultaneously and spaced within the band to be displayed.  An input signal is split and each resulting portion is passed down a tapped delay line, samples at the taps being processed by separate arithmetic units.  The output of each arithmetic unit is applied to the taps of output delay lines which are similar to the input delay lines.  Each arithmetic unit weights the input samples with a set of coefficients and sums the resulting signal in a prescribed manner, thus transforming the signal into the frequency domain, according to a discrete Fourier Transform.  The resulting sums are the real and imaginary terms of a signal which are vectorially added, resulting in a signal which is fed to the ordinate of a display having a swept time base representing frequency.

Abstract: A DELTA MODULATION DETECTOR                        ABSTRACT     A detector for detecting a delta modulated signal includes a timing circuit, a counter and a decoder arranged to detect a delta modulated signal in electrically noisy environment.  The timing circuit is used to provide a timing signal of a predetermined time interval over which the counter counts the transitions present in the delta modu-lated signal.  The counter is used for counting the digital bit occurrences of the delta modulated signal within the predetermined time interval.  The decoder responds to the timing signal and receives the count signals from the counter and provides a binary signal of first state when the count signal indicates the number of bit occurrences of the delta modulated signal is above a predetermined high level of count or below a predetermined number of low count and provides a binary signal of a second state when the count signal indicates that the number of the digital bit oc-currences occur between the predetermined high level of count and the predetermined low level of count.  The de-tector is further provided with a latch circuit which responds to the output of the decoder and a code detect signal representing detection of a predetermined code signal in delta modulated signal.  The latch circuit is used to provide an output signal in response to the binary signal of the first state from the decoder and the code detect signal to signify proper reception of delta modulated signal.  The above described detector may be advantageously used in a receiver for receiving a scrambled or unscrambled incoming delta modulated digital data signal.

Abstract: The identification system consists of an electronic key comprising a passive memory area (10) and a shift register (9) and a lock capable of being coupled with the key. The lock is capable of supplying a pulse causing the code contained in the memory (10) to be loaded into the register (9). The register (9) is looped on itself via connection (113). Before reading the contents of the register (9) a set number of clock pulses, counted by the control circuit (149) and transmitted by the electronic lock on the H terminal, produces a series of permutations of the contents of the shift register (9). After this permutation phase, the AND gate (157) allows the data contained in the shift register (9) to flow out through the output terminal S due to the action of additional read pulses the number of which is equal to the number of bits in the register (9).

Abstract: ABSTRACT OF THE DISCLOSURE           A circuit receives a cyclic input signal having a frequency determined by a source, which frequency may vary in accordance with a parameter or condition to be measured, for example.  The circuit very precisely provides an output current representative of the frequency of the input signal. In particular, the circuit uses a pair of regulated and different voltages, one of which is impressed upon an averaging circuit for a preselected time during each cycle of the input signal, and the other voltage is impressed upon the averaging circuit during the time when the first signal is not connected to the averaging circuit.  A control signal is developed from the averaging circuit which is a function of the average of the voltage provided to the averaging circuit, and the control signal in turn is used for control-ling a current control amplifier and transistors which in turn control current flow through a load connected to output terminals and through a feedback resistor. The use of regu-lated voltage sources for deriving the current control sig-nal insures great stability, relatively low cost, and pre-cise operation.
