Feature Descriptions:

Task 1: Signal Generation and Display

This feature allows the user to read samples of a signal from a text file and display it in both continuous and discrete representations. Additionally, it provides the ability to generate sinusoidal or cosinusoidal signals with customizable parameters.

Task 2: Arithmetic Operations

This menu includes various arithmetic operations like addition, subtraction, multiplication, squaring, shifting, normalization, and accumulation on input signals.

Task 3: Signal Quantization

This feature enables the quantization of input signals. The user is prompted to input either the number of levels or the number of bits available. The application then displays the quantized signal and quantization error.

Task 4: Frequency Domain Operations

This menu allows the application of Fourier Transform to any input signal. It displays frequency versus amplitude and frequency versus phase relations. Users can modify amplitude and phase, save frequency components to a file, and reconstruct the signal using IDFT.

Task 5: Discrete Cosine Transform (DCT)

This feature computes DCT for a given input signal, displays the result, and allows the user to choose the first m coefficients to be saved in a text file, also allowing removing the DC component of an input signal.

Task 6: Time Domain Operations

This menu includes operations like smoothing, sharpening, delaying, advancing, folding, delaying/advancing a folded signal, and removing the DC component in the frequency domain.

Task 7: Convolution and DC Removal in Time Domain

This menu provides the ability to convolve two signals and remove the DC component.

Task 8: Correlation Operations

This menu includes features like computing normalized cross-correlation, time delay analysis, and template matching.

Task 9: Fast Convolution and Correlation in Frequency Domain

This feature implements the fast method for convoluting and correlating two signals in the frequency domain using DFT and IDFT.
