ABSTRACT:
Assembly for the display of data, usually an analog signal, generated over a selected time period which includes analog data input, analog to digital conversion to convert the analog data to a digital signal, analog signal input and converter digital signal output, first data latch having an input to receive data from the converter digital signal output, first latch data output, and a first reset input to receive a first switch signal to transfer data from the first latch data input to the first latch data output, first display driver having input to receive the first latch data signal and provide visual indication of the signal at the first latch data output,second data latch having an second latch input to receive data from the first latch data output, and a reset input to receive a second switch signal to transfer data from the second latch data input to the second latch data output, second display driver having input to receive the second latch data signal and provide visual indication of the signal at the second latch data output. A reset signal generator generates the second switch signal and a delay device is provided to receive the second switch signal, delay the signal a selected time and then generate the first latch switch signal.
