1) Generate a .wav file by encoding your contact phone number using DTMF (Dual-Tone Multi-Frequency) signaling with MATLAB. Implementation typically involves using the `audiowrite` function and generating dual-frequency sine waves for each digit. 2) Decode the generated DTMF file to extract the encoded telephone number. This requires implementing a Goertzel algorithm or FFT-based frequency detection to identify the characteristic tone pairs in the audio signal.

Time series forecasting holds significant importance in economics and engineering fields. This study leverages the characteristics of dynamic neural networks to propose a time series prediction methodology, implementing a designed dynamic network to forecast response time series of Duffing's equation. Results demonstrate that dynamic neural networks effectively predict response time series of dynamic systems, with MATLAB implementation utilizing NARX (Nonlinear Autoregressive with Exogenous Input) network architecture and time-delay feedback mechanisms.
