What are the three basic modules needed to perform the project of System Modeling Using LMS Algorithm?
1) A noise signal generator, an unknown system, and an adaptive FIR model
2) A noise signal generator, a sequence of random numbers, and a variance of 1/3
3) A noise signal generator, a sequence of uniformly distributed random numbers, and a power of 1/3
4) A noise signal generator, a sequence of random numbers with zero mean value, and a length of 3000
