REL #39 A €50 PN9 PRBS generator (BER Pt. 4)
This is the fourth episode in a series of videos on Bit Error Ratio (BER) testing. We discuss the design considerations for a DIY PRBS NP9 generator, show the final prototype and do some testing on it.
Resources (code, schematics, NP9 code) are available at https://github.com/RudisElectronicsLa...
