Patent GB-2037523-A (GB)
Title: Frequency Sensing Circuit
IPC: H03H17/08
Filed: 1979-11-22
Abstract: A digital frequency sensing circuit includes a clock generator that operates at a frequency Fc that is N times the desired frequency F0 to be sensed, where N is an integer equal to or greater than two. The amplitude of an input signal is sampled at the clock rate, and each sampled amplitude is converted to a digital word. The digital words are applied to a first input of an adder, and digital feed-back words are applied to a second input of the adder. The output from the adder is applied to a delay circuit which has a delay that is an integral multiple of one-half of the period T0 of the frequency F0 to be sensed. The delayed words are multiplied by some number less than one and greater than zero, and applied to the second input of the adder in phase with the words applied to the first input of the adder. A circuit output signal is derived from the adder output, or from the delay circuit output. This circuit output signal has a magnitude indicative of the frequency of the input signal with respect to the clock frequency, and its magnitude is greatest when the input signal frequency F0 is equal to the clock frequency Fc divided by N. <IMAGE>

Title: Circuit for Discriminating SECAM Television Signals
IPC: H04N9/64
Filed: 1981-09-17
Abstract: A discriminator circuit for a SECAM (Registered Trade Mark) color television receiver comprises a gate (8) for passing at least a portion of each color subcarrier of a received color television signal in response to a gate pulse to a band-pass filter (16) having a passband center frequency tuned to a trough of the characteristic crest-trough pattern of one of the color subcarrier spectrums of the SECAM system, so that the output of the band-pass filter occurs at one-half the line frequency if the received signal is in the SECAM system format. A frequency discriminator (18) provides a signal indicating that the received signal is in the SECAM format when it detects that the output of the band- pass filter occurs at one-half the line frequency to discriminate it from signals of other color television systems. <IMAGE>

Patent GB-2111732-A (GB)
Title: Signal processing arrangements
Inventor: ZETTERBERG CARL PETER
IPC: H04B1/69
Filed: 1981-12-11
Abstract: Coded input signals (e.g. PN sequences), arrive in phase coded form for example on a 70 MHz carrier on a line 5, there being four different coded signals in this example. By means of frequency generator 10 and a mixer 6, the phase- modulated carrier is converted into four waveforms with carrier frequencies F1 = 65.5 MHz, F2 = 68.5 MHz, F3 = 71.5 MHz and F4 = 74.5 MHz which are applied simultaneously to input 17 of a convolver 18. Frequency generator 10 also generates four control waveforms at F1, F2, F3 and F4 which are selected by filters 24 to 30 and a multiplexer 32 and each is modulated by the time-reversed replica of a respective one of the coded input signals. The modulated control waveforms are applied in succession to input 44 of the convolver which has sufficient length to enable all four input waveforms to be compared with all four control waveforms. A maximum convolved output will appear at output 46 when there is correlation alignment between the particular control waveform carrying the time-reversed replica of the coded input signal present. The frequency of this output (detected at 50 to 70) identifies the coded input signal. instead, the control waveforms can be applied simultaneously (Figure 3, not shown). <IMAGE>
