سلام
کد متلب سوال زیر را می خواهم کسی نداره
The Goertzel algorithm can be used to detect single tone
sinusoidal signals. Consider one speech sample, (it could
be music or others). We want to detect single tone signals
of frequencies 490, 1280, 2730, and 3120 Hz in sample.
Sampling frequency consider as 8kHz. The Goertzel algorithm
computes only one relevant sample of an N-point DFT for
each tone to detect it.
a- What should be the minimum value of DFT length N so that
each tone is detected with no leakage in the adjacent DFT
bins. The same algorithm is used for each tone.
