DSP drives speed and accuracy; coherence saves the day - DSP techniques lead to faster, less costly frequency-response tests and enable the use of a powerful concept, the coherence function, which acts as a watchdog to help identify and quantify common but easy-to-miss measurement errors. Best of all, this watchdog works for free. Smart signal conditioners compensate for the errors and extract the true signals from the dross. Pressure transducers, accelerometers, temperature sensors, and linear-position sensors are often imperfect devices, prone to nonlinearities and gain and offset errors.
I've Never Lost the Wonder. This is a noncommercial site operated by Max Robinson and dedicated to passing on and preserving knowledge of vacuum tube circuits and techniques. Keep the electrons flowing and the tubes glowing. Going all in with NVDA. Some may become frustrated at this and give up on NVDA.
