Waveform generator

An electronic system, comprising:

• an array of transducers configured to generate waves in response to driving signals;
• and
• a waveform generator configured to generate the driving signals, wherein said waveform generator comprises:
• a system control unit;
• and
• a plurality of channels controlled by the system control unit and configured to supply a corresponding plurality of driving signals, wherein each driving signal is configured to drive a respective transducer of an array of transducers;
• wherein each channel comprises:
• a sequential access memory having a plurality of rows, wherein each row stores an instruction word configured to generate a respective step of a waveform, and a memory output defined by an output row at a fixed location, wherein the waveform is defined by a block of instruction words;
• and
• an internal control unit configured to sequentially move instruction words 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.
