Abstract
Abstract The invention comprises a system using digital techniques, for retrieving information contained in the amplitude variations of a received signal. The invention comprises a first register which instantaneously tracks the received signal, a second register which tracks the highest and a third register which tracks the lowest value of the signal. The outputs of the second and third registers are subtracted in order to arrive at the information desired.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
149 words
A system for digitally processing a series of received pulses which vary in amplitude according to information contained therein, comprising; analog to digital conversion means for translating variations in the amplitude of said input signal into digital form, a first register for continuously tracking the digital output of said analog to digital conversion means, a second register coupled to said first register, first tracking means coupled to said second register for allowing said second register to track said first register up to its highest value and hold said highest value, a third register coupled to said first register, second tracking means coupled to said third register for allowing said third register to track said first register down to its lowest value and to hold said lowest value, and means coupled to said second and third registers for computing the difference between values contained in said second and third registers.
Claim 2
Independent Claim
149 words
A system for digitally processing a series of received pulses which vary in amplitude according to information contained therein, comprising; analog to digital conversion means for translating variations in the amplitude of said input signal into digital form, a first register for continuously tracking the digital output of said analog to digital conversion means, a second register coupled to said first register, first tracking means coupled to said second register for allowing said second register to track said first register up to its highest value and hold said highest value, a third register coupled to said first register, second tracking means coupled to said third register for allowing said third register to track said first register down to its lowest value and to hold said lowest value, and means coupled to said second and third registers for computing the difference between values contained in said second and third registers.
Claim 3
Dependent Claim
88 words
The system recited in claim 1, wherein said first tracking means comprises; means coupled to said first and third registers for generating a first signal when said first register has a value greater than or equal to said third register, means coupled to said first and second registers for generating a second signal as long as said first register is greater than said second register, and means for allowing said first register to transfer its output into said second register in response to said first and second signals.
Claim 4
Dependent Claim
85 words
The system recited in claim 2, wherein said second tracking means comprises; means coupled to Said first and second registers for generating a third signal when said first register has a value less than said second register, means coupled to said first and third registers for generating a fourth signal as long as said first register is smaller than said third register, and means for allowing said first register to transfer its output into said second register in response to said third and fourth signals.
Claim 5
Independent Claim
74 words
A method to be performed by a machine of measuring the peak amplitude of an input signal composed of pulses varying in amplitude comprising the steps of: continuously converting the varying amplitude of said input signal into a digital output, tracking said output up to its highest value, holding said highest value, tracking said output up to its lowest value, holding said lowest value, and, computing the difference between said highest and lowest values,
Claim 6
Independent Claim
74 words
A method to be performed by a machine of measuring the peak amplitude of an input signal composed of pulses varying in amplitude comprising the steps of: continuously converting the varying amplitude of said input signal into a digital output, tracking said output up to its highest value, holding said highest value, tracking said output up to its lowest value, holding said lowest value, and, computing the difference between said highest and lowest values,
Claim 7
Dependent Claim
54 words
Wherein the tracking to said highest value includes: transferring said output to a first register during the rise time of said output, intermittently generating a first signal after said transfer until said digital output reaches its highest value, and allowing said first register to track said output at each occurrence of said first signal
Claim 8
Dependent Claim
54 words
Wherein the tracking to said highest value includes: transferring said output to a first register during the rise time of said output, intermittently generating a first signal after said transfer until said digital output reaches its highest value, and allowing said first register to track said output at each occurrence of said first signal
Claim 9
Dependent Claim
58 words
Wherein the tracking to said lowest value includes: transferring said output to a second register at a time when said output is less than said highest value, generating a second intermittent signal from said time until said digital output reaches its lowest value, and allowing said second register to track said output upon each occurrence of said signal.
Claim 10
Dependent Claim
58 words
Wherein the tracking to said lowest value includes: transferring said output to a second register at a time when said output is less than said highest value, generating a second intermittent signal from said time until said digital output reaches its lowest value, and allowing said second register to track said output upon each occurrence of said signal.
