Of course if the speech is sampled at 8000Hz our upper frequency is limited to 4000Hz. Then follow these steps: Using equation 1, convert the upper and lower frequencies to Mels. In our case 300Hz is 401.25 Mels and 8000Hz is 2834.99 Mels. NettetBackground/Objectives: Neuropathy is a disorder which will be detected using Electromyography (EMG) signals.
