Abstract

PURPOSE: To extend the dynamic range, by transmitting the digital signal with digital compression converted from the signal in analog compression, converting the digital signal delivered into analog, and restoring to original signal with analog expantion.
CONSTITUTION: The analog signal at the input terminal 1 is made for analog compression processing with the sample hold circuit 2, variable gain amplifier 3, AD converter 4, latch circuit 5 and the level identifying logic circuit 6, analog signal is converted into digital signal, and this converted signal is compressed with the digital compression circuit 7 and it is outputted to the output terminal 8. The signal compressed from the terminal 8 is fed to the input terminal 10, it is expanded with the digital expansion circuit 10, converted into analog signal with the DA converter 11, and further,it is made to analog expansion with the instruction of the level identifying signal C at the variable gain amplifier 12, allowing to be restored into original analog signal and outputted to the output terminal 13.
