I understand enough to think the proposal sounds reasonable, but not enough to know why it is apparently, in fact, unreasonable.

- fanf2 7y agoDigital logic is built from amplifiers with the gain set right up, so that any voltage above the threshold goes to max and any voltage below goes to zero. Very little tuning is needed to get a working circuit, compared to multi-level or analog circuitry. In CMOS, current basically only flows when the circuit is switching between two states, whereas in an analogue circuit it flows all the time, so digital logic can be more efficient. In digital signal transmission, “eye diagrams” are used to visualise the quality of the signal: the eye is the gap between low and high and it needs to be clearly open for receivers to be able to detect the signal with decent integrity. https://www.onsemi.com/pub/Collateral/AND9075-D.PDF https://www.onsemi.com/pub/Collateral/AND9075-D.PDF
