1. The discriminator determines the sign of the output signal of the adder-subtractor.

2. This causes the discriminator output to decrease the capacitive reactance of the varicap.

3. Method for the reconstruction of zero crossing information of noisy angle-modulated signals following limiter-discriminator signal processing

4. The foundation of this investigation is a Batse data product labelled with the ac-ronym DISCLA for large area discriminator data

5. In addition to 'hopping' of IP addresses and discriminator fields, hardware addresses such as Media Access Control addresses can be hopped.

6. This signal is applied to a frequency-sensitive discriminator that produces an output voltage proportional in amplitude and polarity to any change in AFC-IF frequency.

7. Each pixel (19) has an electronic conversion device (20) for converting an analog measuring signal of the pixel (19) into a digital measuring signal, said device comprising a discriminator for background suppression.

8. To perform this it is not necessary for the ear to work as an accurate frequency-discriminator in the steady state, but the possibility to detect quick amplitude and frequency changes must be developed exquisitely.

9. Automatic frequency control circuits mix an attenuated portion of the transmitted signal with the local oscillator signal to form an IF signal. This signal is applied to a frequency-sensitive discriminator that produces an output voltage proportional in amplitude and polarity to any change in IF-frequency.

10. In order to ensure, in a protective device for monitoring and securing accesses to danger areas in stores, especially at the entrances to lanes in high-shelving stores, that, on the one hand, vehicles passing across the access are recognised before they enter the danger area and trigger alarm signals and, on the other, vehicles passing by the lanes or accessways do not trigger said alarms, it is proposed to fit the vehicles with a signal transmitter which transmits a bunched, coded signal received by a fixed signal receiver arranged in the access to the store and taken to a control device, said control device's comprising a discriminator suppresses other than correctly coded output signals, and the monitored access is outside danger areas.
