Table 3 shows the detected tones with NDFET implemented on the ADSP-2101.
For the implementation, we used an adaptive step size
over each 
interval of 
samples,
, with 
.
As shown on Table 3, estimation errors are very high since this
algorithm is not robust in the presence of noise.
Although NDFET is much faster than the Goertzel algorithm, it does not
meet the standard 2(a).
