Answer / pradeep
Dirac delta is a continuous time function with unit area and
infinite amplitude at t=0.
the fourier transform of dirac delta is 1.
using dirac delta as an input to the system, we can get the
system respnose. it is used to study the behavior of the
circuit.
we can use this system behavior to find the output for any
input.

Answer / roy vincent
a dirac delta function has a strength = 1. Consider a signal in time domain, its fourier transform will give its frequency contents with proper weightage. A dirac delta function has all frequencies in equal amplitudes. So this can be used to analyse the system behavior. In fact u can find out the system transfer function, which can be applied to any arbitrary input and predict its output.

Answer / s.v.rupesh
actually dirac deelta function is for output of the impulse response in time domain if u give fourier transfoemation it will be the same .. i guess
