Classification of Continuous Time signals and Discrete time signals?

Answer 1

we often confuse our-self with continuous time and analog signals.

An analog signal is a signal which can take any amplitude in continuous

range that is signal amplitude can take infinite values on the other hand

a digital signal is one whose amplitude can take only finite numbers of values

THE TERM CONTINUOUS SIGNAL AND DISCRETE SIGNAL CLASSIFY THE SIGNALS

ALONG THE TIME (i.e. horizontal axis) where as THE TERM ANALOG AND DIGITAL

SIGNAL CLASSIFY THE SIGNAL ALONG THE AMPLITUDE (i.e vertical axis)

Answer 2

Analog IS a continuous signal.

It provides information transmission by being changed from it's steady-state by the "overlaid" voltage "interferance" of the data "signal".

Think of the surface of a lake as a steady state signal (like a pure 12volts from a battery). Now add the change of a boat that someone is jumping up and down in (the data). The data signal "rides" the surface of the lake water/steady state and is "transmitted" that way.

So, again, the lake surface is the steady state (the water level is above the "ground level" of the lakebed) but the data rides on top in the form of a changing level that goes higher and/or lower than the steady state (again, above the "ground"). Simple, yes?

For all intents and purposes, Digital signals switch rapidly between off and on (and are therefore not continuous by definition) and the pattern of on/not-on contains the data.

Hope this helped.

Answer 3

well....they are classified into six types,they are:

Periodic and aperiodic

Odd and even

Deterministic and random

causal and non-causal

Finite and infinite

Analog and Digital

Answer 4

continuous time signal varies linearly in a continuous flow while discrete time signal flow at discrete instant of time.

Answer 5

A: NO it can stop all together like a loss of a signal
