System Identification using LMS algorithm

To identify a unknown sytem with an FIR filter

You are now following this Submission

If u know the inputs and outputs of an unknown system, the u can identify the system with an FIR filter.

Make the input range between [-0.5 0.5] and find its corresponding responses.

Here in the program, we are assuming a system and finding its response. Using the outputs and inputs of the above assumed system we will estimate a system.

The goal is achieved if the corresponding assumed and estimated systems coefficents are same.
