Time Delay

Hi guys

I wanted to know if it is possible to delay a signal by say,1s, and give the same signal back..

What i mean is ..... i send a signal "S".... after 1s i want to use "S" in the circuit..

If possible could anyone give me the circuit.....

Time Delay

Possible yes, but limited in terms of signal bandwith and dynamic. Assuming you mean an analog signal, the best
way is most likely by digital processing. Previously, magnetic tape loops have been used for delays in the seconds range.

Ya i mean analog signal......or is it possible to store the value of voltage at a given point and time and use it after 1s or even 0.1s (anything is fine)

The problem isn't specified clearly. To delay a continuous waveform, an analog or digital delay circuit is necessary, as already said. To store a single voltage value, a sample&hold circuit may be suitable.
