Class Information
Number: 341/72
Name: Coded data generation or conversion > Digital code to digital code converters > To or from nrz (nonreturn-to-zero) codes > To or from delay modulation code (e.g., miller code, three frequency code, mfm code)
Description: Subject matter for converting digital signals to or from other digital signals wherein a one is encoded as a transition in the middle of a bit cell and a zero is encoded as a transition at the start of the bit cell except there is no transition after a one.
