资 源 简 介
Using Matlab to develop a piece of software able
to produce what is colloquially referred as ‘Shannon Speech’.
The input signal, which is digital, is band-pass filtered
into a number of channels. The output of each filter is half-rectified,
low-passed filtered and multiplied by white noise. Then the result in each
channel is filtered again by another band-pass filter. Finally, the channels
are added to form the output.
Generate a signal of frequency 500Hz, 1500Hz and
2500Hz. Using the STM32F407 board to design a filter bank able to remove each
of the three frequency components.
