Tiivistelmä
An efficient digital signal uses an 8-bit embedded processor on a DSP platform, which was developed to design the technical specifications in this final year project.
The goal was to design a program that counts maximum bits time of 8, 16, 32 and 64 on a Matlab platform, specify the filter design and generate the C header as an export bit integer signed or unsigned, copy the filter coefficients to a platform called PSoC, and initialize with the coefficients generated by Matlab.
The properties were compared with standard and optimized FIR filter designs. How complementary FIR or IIR filter pairs could be utilized more generally in the front-end
processing of digital filters was also studied. In the project a program was designed that counts maximum bits on Matlab, and the filter coefficients were copied to PSoC as one data sample return time. The programming process takes a few seconds to display the result to the screen. During the study on efficient digital filters it was discovered that a DSP processor uses a signal that comes from the real world.
