An interesting thing about logic gates is that they are actually very high gain amplifiers that are designed to switch very fast when the input threshold is crossed. If the inputs are biased to the threshold voltage they will become sensitive to extremely small changes in voltage.
Logic devices are often used as analog amplifiers and examples of circuits are on the internet and experimenters cookbooks.
logic can be biased to produce robust logic level pulses from low level signals...such as converting baseline instrument noise to random data for computers. This data can in turn be used to drive speech synthesizer circuits.
