how to find out that which waveform is continious and which one is discrete...........u cn answer me on Anshe217@gmail.com

Question

anonymous · Answer

a continuous waveform has defined amplitude(value) for every instants of time (under consideration)... for ex: sin(t) is defined for every values of t... 
But a discrete time is not defined for all instants of time... that is it will have a value at certain points of time and does not possess a value for the rest of the time...
