60Hz notch filterAbstract: DSP56311EVM external audio signal is first applied into an input of the EVM board. A 60Hz signal is generated by the DSP Both the external signal and the 60Hz signal are added producing a digital audio signal with an . apparent 60Hz hum. The resultant signal is then sent to a digital 60Hz notch filter which removes the 60Hz , any questions, please contact the DSP Technical Support organization via email at: 60Hz , . The memory can be used to store userbootable code. Filter Test Demonstration (fltr_tst.asm
