Title:
DIGITAL FREQUENCY DIVIDER
Document Type and Number:
Japanese Patent JPS5456759
Kind Code:
A
Abstract:
A simple and reliable digital frequency divider for non-integer rational divisors using a signal polarity switch commanded by an auxiliary counter which derives its counting pulses from a main N-position counter. For such complex divisors the generation of phase leads by toggling the signal polarity switch can be delayed or some phase leads can be suppressed by using relatively low-frequency delay pulses, to avoid large auxiliary counters. Video timing circuits are described based on digital frequency dividers of such types.
