Title: Circuit recognising spurious telegram signs - uses 5-bit binary counter, one bistable and logic gates only
Inventor: KUEHL WERNER ING GRAD
IPC: H04L1/20
Filed: 1979-11-02
Abstract: An evaluation circuit produces a short spike from an Exlusive OR gate (7) at each zero passage of the communication wave. Every time such a spike occurs a counter (1) is reset and a clock input at a rate of 28.8 kHz begins to acount anew. If, for instance, the signal frequencies vary between 900 and 2400 kHz, a genuine spike at OR gate (2) cannot occur outside certain counting limits. The time areas are represented by the count outputs 2, 2 squared, 2 cubed, 2 to the power of 4 in conjunction with a D-Flip Flop (3) OR gate (4) and an AND gate (5). Up to the count '6', the not-Q output remains high, so that the delayed input of the AND gate remains high. If a pulse output at the reset terminal (R) appears it can only be a false signal, and AND gate (5) produces a 'Defect' signal output pulse. After the 6th count pulse the bistable (3) alternates and the signal spike from a genuine signal coincides with a low not-Q. If the count reaches 2 to the power of 4 a reset pulse again produces a defect signal.

Title: Integrated double push=pull modulator with operational amplifier - with feedback loop to common resistive inverting input and transistor switched generator feed to non-inverting input
Inventor: SCHEMMEL HANS-ROBERT DIPL ING
IPC: H04L27/04
Filed: 1979-12-13
Abstract: The circuit provides improved negative swing at the output for a given negative input. The non-inverting input (P) of the op.amp. (OV) is connected to the modulating signal input via a resistor (R1) and the inverting input (N) is connected to the same signal input via a resistor (RO). Feedback from the op.amp. output is fed to the inverting input (N) via a resistor (R). The value of the feedback resistor (R) and the inverting input (N) resistor (RO) are equal. A pulse generator is connected to the non-inverting input (P) by the collector of a buffer output transistor (T1). A second transistor (T2) is common base connected from the output of the pulse generator to the transistor feeding the op.amp. The first transistor (T1) is npn and the second (T2) pnp. The two transistor (T1,T2) buffer switch to the non-inverting input (P) prevents the first transistor (T1) conducting until the input voltage drops below-7 volts compared to conventional 0.7v, and provides a tenfold margin against output distortion.
