| Dec 24, 2019 at 21:44 | comment | added | Duncan C | You want to convert the input into a sine wave? It's pretty simple to filter a PWM signal into a varying voltage, but getting a variable sine wave out of it might be asking too much. Are you looking to vary the frequency of the output wave with the input, the amplitude, or both? And what frequency of sine wave are you hoping to generate? | |

| Jan 2, 2018 at 14:43 | comment | added | Jack | @sa_leinad: please check the edited picture. I have added my circuit diagram. I have a hall sensor which varies its output voltage with respect to the magnetic field. This output is connected to the Comparator. which outputs a digital signal. | |
| Jan 2, 2018 at 6:50 | comment | added | jsotola | please describe the signals at the comparator inputs and how they relate to the final analog output | |
