Abstract
Based on direct digital frequency synthesis technology,using Altera's CycloneII family EP2C5Q208 as the core chip,a type of adjusted frequency and phase position signal generator was designed.The signal generator produces sine wave,square wave,triangle wave,and sawtooth wave.The simulation and hardware verification results show that the signal generator is accurate in precision and has agood anti-jamming ability.The design is of certain practical value.
