Dear Sir,
I am working with TMS320f28335 and trying to implement digital low pass filter for 50 HZ signal, Implemented IIR filter but the output is same as the input.
Simulated same signal on Pspice and it shows the correct output as attached in text file. Please guide me how to get filter coefficients for LPF.
Fs=18200 Hz,
Fc=50 Hz
N=5
Input Signal
sineval=1*sin(Rad)+ 0.03*sin(3*Rad)+0.5*sin(5*Rad)+0.2*sin(7*Rad)+0.02*sin(9*Rad)+0.11*sin(11*Rad)+0.1*sin(13*Rad);
sineval=1*sin(Rad)+ 0.03*sin(3*Rad)+0.5*sin(5*Rad)+0.2*sin(7*Rad)+0.02*sin(9*Rad)+0.11*sin(11*Rad)+0.1*sin(13*Rad); //Q15
Rad =Rad+0.02453125;
array_ir[ConversionCount]=sineval;//abc_dq0_pos2.d;
firFP.input=sineval;
firFP.calc(&firFP);
array_iy[ConversionCount]=firFP.output;
Please suggest how to solve this issue.
