%Step 1: Get the b0, b1, b2, a0, a1, a2 parameters from the formula Audio-EQ-cookbook.
%Step 2: Normalize the b0, b1, b2, a0, a1, a2 to get the b0_a0, b1_a0, b2_a0, a0_a0, a1_a0, a2_a0, k

% Fill b0_a0, b1_a0, b2_a0, a0_a0, a1_a0, a2_a0 in PPC3 for configuration.	
		
		
% if you want to translate the coefficent to Hex vaule rather than
% using our PPC3, you can use following formulat to get the HEX coefficient
% and then wirte them to related register

Step 3: Transfer the b0_a0, b1_a0, b2_a0, a1_a0, a2_a0 to 32bit 2's complement
[B0,B1,B2,A1,A2] = dec2hex(mod(min(round(2^(32-1)*[ b0_a0, b1_a0, b2_a0, a1_a0, a2_a0]),2^(32-1)-1),2^32));

Step 4:  Write the [B0,B1,B2,A1,A2] to the right register address, multiply the value ‘k’ back in the step 2 to the volume register or the b0, b1, b2 of 15th BQ.
