| description | This article presents automatic level control system for the HF
radio-transmitting devices implemented on the basis of the
inexpensive of the audio codec and field-programmable gate
array. The presented automatic level control system provides
a quick recovery of the output level without significant
surge. А compression algorithm based on the Hamming
window function is used to correct the spectral mask of
the signal and increase the mean-square average power of
the radio-transmission path. In conclusion, the results of
laboratory tests of the offered of automatic level control
system. |
