Title: Electrical pulse generator
IPC: G01R13/34
Filed: 1971-09-24
Abstract: 1357025 Pulse train and waveform generating circuits INTERNATIONAL BUSINESS MACHINES CORP 24 Sept 1971 [30 Sept 1970 (2)] 44582/71 Heading H3T [Also in Divisions G1 and G4] A signal generator comprises means to generate a plurality of pulse trains, selectively operable means to delay selected ones of the trains and means to form, at a plurality of outputs, pulse trains or waveforms which are algebraic or logical combinations of particular ones of the delayed trains. The pulse generator may comprise a plurality of computer controlled serial registers 210A-N, which preferably produce a pulse train after a single clock pulse. The output of each register is passed through respective computer controlled delay means 250A-N and to a logical or algebraic combiner 30 providing a plurality of different outputs. A computer controlled pulse-shaper 400 comprises a plurality of pulse-shapers which may increase the rise and fall times of the pulses of the combined pulse trains. In the case of logical combination the pulse shapers also determine the logic voltage levels. A feed back means 600 is used to sample the resultant waveforms and compare it with desired waveforms in a memory of a control computer 100 which corrects the delay times or pulse shaping if necessary. The resultant pulses may be used to stimulate an integrated logic circuit 500 and the various output pulses of that may also be sampled and checked for correct operation. The delay means comprise delay elements (D 1 -D 10 , Fig. 3, not shown) controlled along line (720) by the computer. The pulse combining means may comprise conventional logic circuits with or without "weighted" outputs (Fig. 4, not shown). The pulse shaper means (Fig. 6, not shown) include for each resultant pulse train a logic voltage level setting means comprising a current switch (456) connected to computer controlled means (410, 430) which respectively determine the lower and upper logic levels and supplies a computer controlled D.C. level. Each D.C. level source comprises a digital to analogue converter (D.A.C.). A diode (450) controlled by the current switch is forward or reverse biased to effect connection of the appropriate D.C. level to the output. A switchable attenuator and inductive/capacitive circuitry which determines the rise time of the pulses is also included. An alternative embodiment of the signal generator (Fig. 2, not shown) selectively delays the clock pulse to each signal register by placing the registers after the controllable delays. A time coherent sampling system may be used as the feed back means, waveforms being simultaneously sampled on to storage capacitors and the potential of the capacitors then converted to digital information which is temporarily stored in a respective register and then in a permanent memory. A multiplex system and only one register may be used. Alternatively, the waveform sample may be compared with a reference potential set on a respective storage capacitor by detecting the change in potential of the capacitor when it is connected to the sample.

Abstract: 1,207,130. Multipliers. R. E. CLAPP. 3 Oct., 1967 [17 Jan., 1967], No. 45035/67. Heading G4G. Signals C, D to be multiplied are applied to mechanical or electronic switches S 1 , S 2 , which are square wave operated one in time quadrature with the other, alternately passing respective signals unchanged and with inverted polarity to summation network 3, whose output is amplified at 4 and applied to a peak, linear, or square law detector 4 also filtering residual F components. The resultant is amplified at 6 and applied to synchronous detector 7 whose filtered output represents the product CD, applied to utilization network 8. A crystal controlled square wave generator 20 at twice switching frequency controls the synchronous detector and is differentiated at 21 to produce alternately poled spikes (Fig. 3, not shown) of which the positive and negative excursions are extracted by poled rectifiers 22, 23. The positives are applied to a bi-stable multivibrator MV 1  alternately switched ON and OFF by the input pulses while the negatives are applied over mechanical or electronic relay switch R operated by the output of multivibrator MV 1  for alternate application to two inputs of bistable multivibrator MV 2 , operative to drive the latter OFF from ON or retain it OFF, and to drive to ON from OFF or retain it ON; respectively according to the position of the relay. The multipliers control respective switches S 1 , S 2  and it shows that for connective quarter cycles, so that the second and fourth squares are inverted in polarity by the synchronous detector and the output is approximately equal to 8CD. The switching S 1 , S 2  may comprise a transformer primarily energized by an input with an earthed centre tapped secondary whose ends are alternately selected by an oscillatory switch arm of a relay, multivibrator energized (Fig. 4, not shown). In a modification (Fig. 2, not shown), the switch outputs may be split by a hybrid into sum and difference signals which are amplified and applied to dual detectors whose outputs are differenced, amplified, and applied to the synchronous detector. In radio telescopes, a receiver is switchable alternately between the antenna and a local noise source, and a hybrid is utilized to sum and difference the antenna signal voltage A and the local noise voltage B so that and the averaged product #CD = | A | <SP>2</SP> <SP>-</SP>| B | <SP>2</SP> obtained by the apparatus representing the difference between signal and noise powers is utilized as degenerative error signal to control the local noise power until the error vanishes, when the local noise power = incoming signal power.
