Claim 10:
11. A method to produce an ultrasound signal by an ultrasound system comprising:
a mobile device comprising a display unit, and
an ultrasound imaging device in communication with the portable device and comprising:
a plurality of ultrasound transmission units comprising a first ultrasound transmission unit and a second ultrasound transmission unit, and
delay circuitry comprising:
a first group of chained delay units, and
a second group of chained delay units;

the method comprising:
producing, using the first group of chained delay units, a first plurality of signals each delayed by a different amount, and outputting one of the first plurality of signals to be used for driving the first ultrasound transmission unit;
producing, using the second group of chained delay units, a second plurality of signals each delayed by a different amount, and outputting one of the second plurality of signals to be used for driving the second ultrasound transmission unit;
wherein the first and second groups of chained delay units are interconnected such that:
the first group of chained delay units generates a first signal delayed by a first amount,
the first group of chained delay units outputs the first signal to the second group of chained delay units,
the second group of chained delay units receives the first signal from the first group of chained delay units, and
the second group of chained delay units generate a second signal by delaying the first signal by a second amount.
