  • Circuit arrangement for determining and analyzing the phase interference-modulation of a measuring signal
    Patent number: 4129831
    Abstract: A circuit arrangement for measuring the phase modulation disturbance of a test signal which is passed through a test object and wherein a heterodyne oscillator supplies an input to a mixer which receives the input signal and supplies an output to a detector and display device and wherein the output of the mixer is applied to an automatic frequency control loop including a reference oscillator and a phase discriminator and wherein the output of the phase discriminator is supplied to a detector which supplies an input to a voltage comparator that also receives a reference voltage and which produces an output signal during the overshooting of the reference voltage by the output voltage of the phase discriminator and wherein a pulse counter which counts the occurrence of such overshoots is provided.

  • Tunable oscillator with high stability and accurate frequency
    Patent number: 4121170
    Abstract: A tunable oscillator with high frequency stability and accuracy which utilizes a counter that periodically checks the actual value of the frequency and depending upon the count reached in the counter stage produces one of two logic output signals such that the first signal is formed on the occurrence of a number from a first correlated number sequence which indicates a frequency deviation from the desired value in a first direction and the second number is formed on the occurrence of a number which deviates from the desired frequency in a second direction and wherein logic signals are used to directly or indirectly recharge a capacitor at varying time constants depending upon the frequence drift.

  • Circuit arrangement for measuring the phase modulation disturbance of a test signal
    Patent number: 4050014
    Abstract: A circuit arrangement for measuring the phase modulation disturbance of a test signal which is passed through a test object and wherein a heterodyne oscillator supplies an input to a mixer which receives the input signal and supplies an output to a detector and display device and wherein the output of the mixer is applied to an automatic frequency control loop including a reference oscillator phase discriminator and a low pass filter which supplies an input to the frequency control input of the heterodyne oscillator.
