Since an LTI system output signal carries all the information about a system plus noise, upon considering the system output signals as non-Gaussain noise, it is possible to estimate the system impulse response by. Digital signals are by essence sampled signals. Discrete-time systems A discrete-time system is a device or algorithm that, according to some well-dened rule, operates on a discrete-time signal called the input signal or excitation to produce another discrete-time signal called the output signal or response. Modern telecommunication centres on the problems involved in transmitting large volumes of information over long distances without damaging loss due to noise and interference. PowerPoint help.
