Education
Ph.D. 1976, Electrical & Computer Engineering, Princeton University
M.A. 1975, Electrical Engineering, Princeton University
M.S. 1974, Electrical Engineering, Princeton University
B.S. 1971, Electrical Engineering, National Taiwan University

Research Interests
My research interests are in the general areas of communications and signal processing. We are particularly interested in the practical aspects of the theory and applications of advanced digital signal processing techniques. These include applications in adaptive signal processing, medical signal processing, instrumentation and measurements, audio/video applications, data compression, and A/D & D/A converters. The following are some representative research topics:

--Digital sampling-rate conversion for audio applications
--Signal reconstruction with jittered data
--High performance low cost digital audio equalizers
--Digital adaptive notch filter for mobile phone applications
--SNR measurement techniques with more than 100 dB dynamic range
--Spectral analysis of nonuniformly sampled signals
--Spectrum resolution enhancement via nonuniform sampling techniques
--Improved A/D effective-bit algorithm

Jeff Hoffman & Don Tornquist have been chosen for the 2009-2010 ECE Undergraduate Honors Program. The program enables undergraduates to go beyond their normal studies to work with faculty in the area of their choice: research, entrepreneurship or innovation.

Robert Daasch

Dr. Robert Daasch has won the Semiconductor Research Corporation 2009 Technical Excellence Award. It is the second highest research award in the SRC. The Technical Excellence Award was established as an incentive and recognition program for research of exceptional value to GRC members. Authorized by the Board of Directors in December 1991, the award is intended to complement the Inventor Recognition Award. The Technical Excellence Award is shared among key contributors for innovative technology that significantly enhances the productivity/
competitiveness of the semiconductor industry. To date 25 research efforts have received the award. The 2008 Technical Excellence Award was presented to a team of researchers from Portland State University led by Professor W. Robert Daasch, and supported by students Liwei Ning (PhD 2009), and Amit Nahar (MS 2006) for their research, "Burn-in Reduction: Improving Outlier Screening".
