Abstract
An apparatus relating generally to signal analysis is disclosed. In such an apparatus, a first comparator is coupled to receive a signal input and a first input level. A second comparator is coupled to receive the signal input and a second input level different from the first input level. A time-to-digital converter is coupled at a first port thereof, such as a start port for example, to receive a first output from the first comparator and coupled at a second port thereof, such as a stop port for example, to receive a second output from the second comparator. The time-to-digital converter is coupled to provide digital words representing the signal input.
