It contains an equalizer to reduce frequency distortion
, and supports online video streaming.
By estimating the channel characteristics, this block equalizes the frequency distortion
due to the multipath4 delay spread.
In specialty applications, where sound attenuation with minimal change in frequency distortion
is necessary, custom molded earplugs may be required.
Noise and frequency distortion
can seriously undercut the intelligibility of human speech even though its audibility is good.
Several noted designers aver that the cascode is important to reduce high frequency distortion
and have written text books (the Self text mentioned) and journal articles that discuss this issue.
Note that both devices show similar low frequency distortion
, with the GaAs MESFET switch exhibiting significantly less distortion at high frequencies (higher IP3) than its silicon counterpart.
The low frequency distortion
is constant, with improvement in distortion intercept point at the higher frequencies.
Possibilities of compensation of phase frequency distortions
