Removing Bias in Simulink using math operations

I have a model where I read a signal from a sensor, but the signal is corrupted with noise and bais, I managed to remove the noise by using a filter (BPF).

Now I need to get rid of the bais so can you help me please, I'd really appreciate it.

hello

well, how do you know it's biais and not good data ?

if you have already applied a BPF , there is not dc or linear trend / shift anymore in the signal , so what do you want to do ?

Thanks for your response

Well, I know that because I had to model a real world sensor so after the singal reading I did add a Gaussian white noise and a Bias to the sensor signal

now I have to make a sensor processing system i.e i have to use a filter and emove the bias, Can i use the Mean block in simulink to do so ? and if yes how ?

hello

I thought you had already implemented the BPF for that purpose ? then use it !
