Hi,
We are trying to design a Delta Sigma ADC. As you might know, Delta Sigma ADC consists of a Delta Sigma Modulator and a filter. We have designed the Delta Sigma modulator using Hspice tool and now we want to design the Sinc3 filter using MATLAB. Could you kindly help us in understanding and designing SINC3 filter.
Our original input was a sine wave of 1KHz frequency. Delta Sigma modulator oversampled it by an OSR of 300. We now have a bitstream as output of modulator. We want a low pass filter with cut-off 1KHz and decimation factor of 300 and we want to use the SINC3 filter to perform this. Please help us design this SINC3 filter.
Thanks in advance.
Regards,
abdj
