Hello, I have used matlab to create a filter with response as shown bellow.
using matlab i created the attached file with the coefficients
csvwrite('FilterCoef.txt',Num)
i have created a stepped response as shown bellow,after that i am olanning to connect the DAC output to ADC input.
then i have an array of a samples and i do a convolution between the sampled array and the filter array.
two question are rising afterwards:
how many ADC samples do i need for the convoltion to do correct filterring?
How then i present the filtered data?(sending it again to DAC?)
Thanks.
