DSP Blockset

Transforms

The Transforms library provides blocks for a number of transforms that are of particular importance in DSP applications:

• Analytic Signal
• Complex Cepstrum
• DCT
• FFT
• IDCT
• IFFT
• Real Cepstrum

First and foremost among these are of course the FFT and IFFT blocks, which respectively implement the fast Fourier transform and its inverse. These blocks are discussed further in the next section.
