A signal with a value that can take any value, typically between two limits. We say such values are \u2018continuous\u2019, i.e. there are no intervals or steps. An example is shown below. Here a signal \"v_s(t)\"\u00a0represents a voltage that is changing with time \"t\". The signal can take any<\/b> value such that \"V_L \leq V_s(t) \leq V_U\", where \"V_L\" \u00a0and \"V_U\"\u00a0are the lower and upper limits.\u00a0<\/span><\/p>\n

All electrical systems are ultimately analogue when you look closely enough. I contrast, digital systems employ high-gain amplifiers to switch between two extremes very quickly, giving the impression of working in only two states.<\/p>\n
