Gray Model Prediction with MATLAB

This MATLAB implementation of Gray Model prediction allows users to specify the number of forecast years through a simple graphical interface input. The program utilizes GM(1,1) modeling methodology for time series forecasting.

Non-Return-to-Zero (NRZ) Line Coding with MATLAB Implementation

After launching the MATLAB interface, execute the program to receive a prompt for NRZ code input. Enter binary sequences as arrays, then the system automatically generates encoding and decoding results for CMI, AMI, and HDB3 line codes. The output provides clear comparisons between pre-encoding and post-encoding states, demonstrating waveform transformations through visualization functions and encoding algorithms.

MATLAB FIR Filter Design Program with Code Implementation

A MATLAB-based FIR filter design program featuring an intuitive graphical interface with comprehensive parameter configuration capabilities. The implementation includes various filter design algorithms like windowing method, frequency sampling, and equiripple design using functions such as fir1, fir2, and firls.
