I have built a one bit Sigma Delta ADC. So, I am now trying to increase the resolution of the ADC by using a digital filter which consists of a Binary counter connected to a PIPO shift register.
The red graph is the output of the counter and green one is the output of a shift register. How do I calculate the resolution or the number of bits from the below graph?
The clock frequency of the Sigma delta is 18.8kHz.
