About David

I'm an electrical engineer with an MS degree and an emphasis in DSP.
I love technical challenges involving audio and data communications at the layer 1 level.
I have worked for my whole career on products and projects that require care and attention to provide excellent solutions to customers problems.
I have worked extensively on applications that require adaptive filtering for either echo cancellation, system identification or equalization.
I look forward to helping you solve your complicated problems.
