Abstract
Abstract A transient signal processing circuit is disclosed which includes a signal input, an adjustable threshold detector for selecting from the signal input a signal portion having at least a minimum amplitude, a peak value detector connected to the threshold detector for providing an output when the signal portion reaches a maximum amplitude, a monostable multivibrator connected to the peak value detector to introduce a time delay and thereby allow the output to stabilize, a sample and hold circuit connected to the multivibrator to record the value of the maximum amplitude, and a clock connected to the multivibrator to indicate the time at which the maximum amplitude was attained.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
94 words
A transient signal processing circuit for analyzing a signal input, comprising: a threshold detector for selecting from said signal input a signal portion having at least a minimum amplitude; a peak value detector connected to said threshold detector for providing an output when said signal portion reaches a maximum amplitude; a sample and hold circuit for holding the value of said signal input upon receiving said output and thereby recording the value of said maximum amplitude; and a clock for receiving said output to indicate the time at which said maximum amplitude was attained.
Claim 2
Dependent Claim
94 words
A transient signal processing circuit for analyzing a signal input, comprising: a threshold detector for selecting from said signal input a signal portion having at least a minimum amplitude; a peak value detector connected to said threshold detector for providing an output when said signal portion reaches a maximum amplitude; a sample and hold circuit for holding the value of said signal input upon receiving said output and thereby recording the value of said maximum amplitude; and a clock for receiving said output to indicate the time at which said maximum amplitude was attained.
Claim 3
Dependent Claim
59 words
The circuit of claim 1, further comprising: a monostable multivibrator connected to said peak value detector and providing said output to said sample and hold circuit and to said clock, said multivibrator being adapted to introduce a time delay to allow the value of said maximum amplitude to stabilize before it is recorded by said sample and hold circuit.
Claim 4
Dependent Claim
48 words
The circuit of claim 2, further comprising a digitization signal output from said multivibrator for connection to an analog to digital converter to initiate the conversion of said maximum amplitude value and the time of said maximum value to digital quantities for further analysis by a digital computer.
Claim 5
Dependent Claim
20 words
The circuit of claim 1, wherein said threshold detector may be adjusted to vary the value of said minimum amplitude.
Claim 6
Dependent Claim
122 words
A transient signal processing circuit for analyzing a signal input, comprising: an adjustable threshold detector for selecting from said signal input a signal portion having at least a minimum amplitude; a peak value detector connected to said threshold detector for providing an output when said signal portion reaches a maximum amplitude; a monostable multivibrator connected to said peak value detector to introduce a time delay and thereby allow said maximum amplitude to stabilize; a sample and hold circuit connected to said multivibrator to hold the value of said signal input upon receiving said stabilized output and thereby record the value of said maximum amplitude; and a clock connected to said multivibrator to indicate the time at which said maximum amplitude was attained.
Claim 7
Dependent Claim
122 words
A transient signal processing circuit for analyzing a signal input, comprising: an adjustable threshold detector for selecting from said signal input a signal portion having at least a minimum amplitude; a peak value detector connected to said threshold detector for providing an output when said signal portion reaches a maximum amplitude; a monostable multivibrator connected to said peak value detector to introduce a time delay and thereby allow said maximum amplitude to stabilize; a sample and hold circuit connected to said multivibrator to hold the value of said signal input upon receiving said stabilized output and thereby record the value of said maximum amplitude; and a clock connected to said multivibrator to indicate the time at which said maximum amplitude was attained.
