These functions had a Gaussian-amplitude and linear-phase, both with respect to the curvilinear coordinate of the curve from which the expansion was performed.
Secondly, to be consistent with [14, 15], [u.sub.n] is expected to have a Gaussian-amplitude linear-phase evolution.
This is equivalent to a constant-magnitude linear-phase
characteristic in the frequency domain.
SoundSaver incorporates technology from the company's SoundSoap line of products, including a patented corrective linear-phase
noise reduction algorithm to help clean up the recording.
"Sigma-delta ADCs include a digital decimation filter that typically offers a linear-phase
response through the audio pass band," explained TI's Martin.
