Hi,
we are trying to implement a system to measure the battery voltage of an inverter. the battery voltage is passed through a low pass filter and then the voltage i measured using pic18 adc pin.and then 500 sample voltages are taken and average voltage is calculated, but it will not get any exact voltage.What is my problem?how can i resolve it? is it FIR or IIR digital filter is needed?
please help to solve this issue?
thanks and regards
