1. Analogue and Digital Signals

Being continuous or having continuous values.

Related to digits or discrete quantities; having a set of discrete values.

Having two values or states; describes a number system that has a base of two and utilizes 1 and 0 as its digits

A binary digit, which can be a 1 or a 0.

A sudden change from one level to another, followed after a time, called the pulse width, by a sudden change back to the original level

A basic timing signal in a digital system; a periodic waveform used to synchronize actions

A logic circuit that performs a basic logic operations such as AND or OR.

A basic logic function that performs inversion

A basic logic operation in which a true (HIGH) output occurs only when all input conditions are true (HIGH).

A basic logic operation in which a true (HIGH) output occurs when when one or more of the input conditions are true (HIGH).

A category of digital integrated circuits having functions that cannot be altered

A category of digital integrated circuits capable of being programmed to perform specified functions

provides robustness and stability to systems, ensuring that changes in input variables do not immediately trigger undesired or erratic responses. By introducing thresholds and memory of previous states, hysteresis allows for more reliable operation and noise immunity in various applications.
