Found this interesting application note “Microstrip and Stripline Design” http://www.analog.com/static/imported-files/tutorials/MT-094.pdf with a formula to calculate PCB traces to have a 75 Ohm impedance: For a given PCB laminate and copper weight, note that all parameters will be predetermined except for W, the width of the signal trace. Eq. 3 can then be used to design […]

Unlike the videobass, where I only have to perfect things I didn’t like in the last version, this is a thing I build from scratch. […]
