4×10 Workbench with Pneumatic Lift

I wanted a large workbench with surface dimensions a bit larger than the standard 4×8 foot material I frequently work on. I also wanted it (almost) rock-solid to do some optics-related work. The workbench is very heavy- but I designed in pneumatic lifters so that I can easily put the bench on wheels when I […]

Computing Data Windows Recursively

Data windows are indispensable for computing the spectral characteristics of signal waveforms that are not periodic in time. In the context of hardware-based digital signal processing, most if not all data windows are expressed in terms of fairly complex function that are not convenient for embedding in a FPGA or custom ASIC. This memo presents […]

New materials added

My 2008 textbook shipped with a CD that had the actual MATLAB scripts that I used to compute/plot every figure in the book. Several written appendices were also made available on the CD, and these have been up-loaded to the Papers section of the site ( Appendix 6C, 6D, and 7A, all under Phase-Locked Loops). […]
