Logic Noise is an exploration of building raw synthesizers with CMOS logic chips. This session, we continue to abuse the 4069UB as an amplifier. We’ll turn the simple unity-gain buffer of last session ...
Sometimes things just don’t make sense! For instance, your RC filter or amplifier’s lowpass filter at the input of a delta-sigma ADC can produce a noisier digital output. Didn’t you design the filter ...
Editor’s note: I came across this excellent tutorial article on Digital Filter Design and I thought it would be an excellent guide for novices as well as seasoned veterans. I want to thank William H.
