Updated title, marked requirements which are now perceived as impracticable, and mentioned why no answer accepted yet.

Added annotations and question adjuncts, as well as removed "Sawtooth wave" requirement, based on answers seen so far.

| Oct 10, 2012 at 10:31 | comment | added | ARF | There is tradeoff between the simplicity of the solution and the accuracy of the transmitted waveform. What is your application? Is it a device metrology problem or an ultrasound problem you are trying to solve? | |
