Abstract

Abstract An electric circuit with a plurality of inputs, each input receiving a train of pulses. Each pulse of each train sets a latch of cross-coupled logic gates to an output of logic 1. A clock generating regular voltage pulses is connected in parallel to the latches so as to reset the output of each gate to logic 0 in series with each other. The plurality of outputs from the latches is passed through a common gate to form the output train of pulses as an addition of the plural inputs.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 207 words
A circuit arranged to respond to a plurality of voltage pulse trains and generate a single voltage pulse train which is an addition of the plurality of trains, including; a first circuit section connected to a first of the input pulse trains, including, a. a pair of logic gate circuits connected as a cross coupled latch and connected to receive the pulses of the input to the section and generate an output logic 1, b. a connection between the output of an independent, stable source of voltage pulses and the cross coupled latch through which a first of the edges of the pulses shifts the latch output to logic 0. c. and a resistance divider circuit means capacitively connected to said latch and responding to only the shift in the latch output to logic 0 to generate a voltage pulse in the output of the circuit; and a second circuit section connected to a second of the input pulse trains which generates a voltage pulse in the output of the circuit with the second of the edges of the pulses of the stable source of voltage pulses, whereby the differential source pulses generates a pulse train output of the circuit from the plurality of input pulse trains.
Claim 2
Dependent Claim 207 words
A circuit arranged to respond to a plurality of voltage pulse trains and generate a single voltage pulse train which is an addition of the plurality of trains, including; a first circuit section connected to a first of the input pulse trains, including, a. a pair of logic gate circuits connected as a cross coupled latch and connected to receive the pulses of the input to the section and generate an output logic 1, b. a connection between the output of an independent, stable source of voltage pulses and the cross coupled latch through which a first of the edges of the pulses shifts the latch output to logic 0. c. and a resistance divider circuit means capacitively connected to said latch and responding to only the shift in the latch output to logic 0 to generate a voltage pulse in the output of the circuit; and a second circuit section connected to a second of the input pulse trains which generates a voltage pulse in the output of the circuit with the second of the edges of the pulses of the stable source of voltage pulses, whereby the differential source pulses generates a pulse train output of the circuit from the plurality of input pulse trains.
Claim 3
Dependent Claim 139 words
A circuit connected to a plurality of voltage pulse trains, including; a section for receiving each pulse train, each section including; a. a pair of logic gate circuits connected to form a cross-coupled latch and receiving the pulse train to the section as one of two inputs, b. a resistance divider circuit means capacitively connected to the output of the latch so as to generate an output voltage pulse as the latch output shifts in a predetermined direction, c. and a source of independent stable, cyclic voltage pulses connected to the latch as the other of the two inputs, a selected edge of each pulse shifting the latch output in the predetermined direction; whereby the output voltage pulses from the circuit means of each section is sequentially formed into an output of the circuit as a single pulse train.
Claim 4
Dependent Claim 139 words
A circuit connected to a plurality of voltage pulse trains, including; a section for receiving each pulse train, each section including; a. a pair of logic gate circuits connected to form a cross-coupled latch and receiving the pulse train to the section as one of two inputs, b. a resistance divider circuit means capacitively connected to the output of the latch so as to generate an output voltage pulse as the latch output shifts in a predetermined direction, c. and a source of independent stable, cyclic voltage pulses connected to the latch as the other of the two inputs, a selected edge of each pulse shifting the latch output in the predetermined direction; whereby the output voltage pulses from the circuit means of each section is sequentially formed into an output of the circuit as a single pulse train.
Claim 5
Dependent Claim 49 words
The circuit of claim 2 in which the pair of logic gate circuits are NAND gates which receive each pulse to their section for generation of an output logic 1 and the circuit means generates its output voltage pulse as the logic 1 output is shifted to logic 0.
