| Abstract: | A new time-gain-compensation (TGC) amplifier has been designed and built. It has flexible and unambiguous TGC-amplification by software steering through digital control and synchronization of this amplification to the clock of the analogue-to-digital converter. It has been built on a single VMEbus board, and enables control of the RF signal as a function of time for ultrasound propagation in layered attenuating media. |
