Abstract
A waveform generator includes a system control unit and signal channels controlled by the system control unit and configured to supply driving signals for driving a respective transducer of an array of transducers. Each signal channel includes a sequential access memory having rows, where each row contains an instruction word configured to generate a respective step of a waveform to be generated. A memory output of the sequential access memory is defined by an output row at a fixed location. The waveform to be generated is defined by a block of instruction words. Each signal channel also includes an internal control unit that is configured to sequentially move the content of the sequential access memory, based on the instruction word currently at the memory output, so that sequences of instruction words are provided at the output row.
