Abstract
Abstract A system for converting an electrical signal to a number of pulses and counting those pulses to provide a digital signal related to the average of the original electrical signal. An accurate electronic clock is included to provide time information and to determine the period of measurement and of averaging. Digitized signal, average, and time information are displayed and provided for interfacing with other digital equipment. An output analog signal is derived alternately from the digitized input signal and from its average.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
104 words
An averaging system for selectively indicating instantaneous and average values of a quantity, wherein a sensor is provided to produce an electrical signal corresponding to the quantity, said system comprising means for converting said electrical signal to a first binary and first BCD signal corresponding to the instantaneous value of said electrical signal over a determined period, means for producing second binary and second BCD signals, a binary bus, a BCD bus, control means for selectively applying said first and second binary and first and second BCD signals to said binary and BCD buses respectively, and digital display means connected to said BCD bus.
Claim 2
Dependent Claim
104 words
An averaging system for selectively indicating instantaneous and average values of a quantity, wherein a sensor is provided to produce an electrical signal corresponding to the quantity, said system comprising means for converting said electrical signal to a first binary and first BCD signal corresponding to the instantaneous value of said electrical signal over a determined period, means for producing second binary and second BCD signals, a binary bus, a BCD bus, control means for selectively applying said first and second binary and first and second BCD signals to said binary and BCD buses respectively, and digital display means connected to said BCD bus.
Claim 3
Dependent Claim
22 words
The averaging system of claim 1, further comprising means for conditioning said electrical signal before conversion thereof, to a determined voltage range.
Claim 4
Dependent Claim
33 words
The averaging system of claim 1, further comprising a digital to analog converter connected to said binary bus to produce analog signals selectively corresponding to the instantaneous or average values of said quantity.
Claim 5
Dependent Claim
15 words
The averaging system of claim 1, wherein said control means includes a real time clock.
