Study Notes
Linear Transformations and DFT
- A linear transformation is a process where signals from one domain are converted to another domain and vice versa, without any loss of information.
- Matrix W is the linear transformation matrix.
- In the context of Discrete Fourier Transform (DFT), linear transformations are used to convert signals between time and frequency domains.
- The DFT is a linear transformation that can be represented by a matrix, allowing for the conversion of signals between domains without losing any information.
