Decompose Signal Using Gammatone Filter Bank Block

R2026b

Use the Gammatone Filter Bank block to decompose a signal by passing it through a bank of gammatone filters.

Connect the blocks as shown in the model.

Use the Random Source block to generate the signal and observe the output of the Gammatone Filter Bank block using the Spectrum Analyzer Block. Configure the Gammatone Filter Bank by setting the block parameter as:

• Frequency range (Hz) — [50 8000]

• Number of filters — 32

• Inherit sample rate from input — off

• Input sample rate (Hz) — 16000

• Bands as separate output ports — off

Run the model and select the Spectrum Analyzer Block to view the output of the Gammatone Filter Bank block.
