speed signal and DRAC

[Peter D. Hipson]

Actually it is not an A/D converter, it converts an analog input to a
digital signal, however the output of the DRAC is not standard TTL, the
input is frequency, not voltage sensitive. Most electronic speedometers
could be driven directly (but inaccurately) from a magentic sender. 

(FWIW, and A/D converter converts varying voltage to a digital value, if
the DRAC did that then the output would not change unless your speed
changed! <g>)
