Abstract: An improved fire alarm system utilizes receiver (10) and fire detecting terminals (20) connected thereto through a signal transmission line (1) comprising two wires. The fire detecting terminal operates on two mode, one being a contact-closure mode of transmitting to the receiver a level signal whether or not a significantly higher fire-indicative quantity is detected, and the other being intelligent mode of transmitting a digital signal indicative of the sensed quantity in the form of a superimposed signal upon the level signal in answer to the instruction from the receiver for precise and convenient analysis thereof in determining fire presence on the side of the receiver. The fire detecting terminal includes a comparator having its own threshold with which the value of the sensed analog quantity is compared for providing the level-shifted signal when the sensed analog quantity has a level higher than the threshold, notifying fire presence independently of the intelligent mode. The threshold level can be selected independently of a criterion utilized in determining fire presence based upon the digital signal on the receiver, so that the above two modes can have the same sensitivity against possible fires. Accordingly, the contact-closure mode can well stand for a back-up fire detection without reduction in sensitivity.

Abstract: In known color-under video recorders intertrack chrominance cross talk is eliminated by comb-filtering of the back-converted chrominance signal. However, if the delay circuit needed in the comb filter is a CCD delay line this will give rise to problems both in respect of production engineering and circuit design. These problems are mitigated by the novel comb filter. Comb filtering is applied to the down-converted chrominance signal. The signal path in which the signal is delayed includes a clocked CCD delay line and a phase correction circuit having a linear frequency response and whose dimensioning is such that the overall delay of the chrominance signal corresponds to the signal periodicity imposed by the signal standard and that the phase shift which occurs in the down-converted signal as a result of the recording standard in conjunction with the signal standard is eliminated. The invention can be applied to PAL video recorders, NTSC video recorders, multi-standard video recorders, and vertical pre-emphasis and de-emphasis in video recorders.

Abstract: Using the novel method, it should be possible to achieve the highest possible data rate for the data to be transmitted in addition to speech. For this purpose, the voice frequency band is split into at least two part-frequency bands at the transmitter end. The part-frequency bands are scrambled with one another and optionally inverted or not inverted. For the simultaneous transmission of additional data, the speech information of at least one part-frequency band is also removed at the transmitter end and replaced by the data to be transmitted. At the receiver end, the part-frequency bands are inverted again or not inverted and descrambled in corresponding inversion with respect to the transmitter end. Finally, the part-frequency bands used for the respective transmission of speech or of additional data are selectively separated and separately evaluated. Simultaneous speech and data transmission.
