Latest Patents

One of Gehrt's latest patents is a circuit arrangement for frequency-modulated picture signals. This invention involves a picture reproducing apparatus that utilizes an amplitude limiter, which processes a frequency-modulated picture signal. The output is coupled to a frequency demodulator, and the design includes a low-pass filter that follows fluctuations in the time-average of the output signal. The delay time of the delay means is crucial, being approximately a quarter of the carrier period of the frequency-modulated picture signal.

Another significant patent is a multivibrator circuit having a compensated delay time. This circuit serves as a delay element, where a pair of complementary signals controls the transistors of a long-tailed pair. The design generates charging and discharging currents for a capacitance, allowing for precise control over the delay time. The innovation includes a current division that enables the circuit to achieve a voltage swing at the output, independent of current adjustments.
