Hi,

does anyone know an detailed description for the implemented low pass filter?

A link for a sufficient windows tool would also be nice...

thx...

Hi Boris,

I don't know what low-pass filter you mean.

There are passive, active, higher-order filters.

You can find many tutorials on the internet, such as

https://www.electronics-tutorials.ws/filter/filter_2.html

Then, you can simulate the filter in PSpice etc.

Regards,

Daniel

Hi,

some weeks ago I added a question regarding the Filter of the MagniV.

Now, I´ve got an additional question....

At page 139 of the manual of the MM9Z1_638 I found the main structure of the implemented low pass filter. In table 192, I found the value conversation: "Data Format: MSB = Sign (“1” minus)"

Does it mean, you are using the twos complement? and is there an excel sheet aviable to calculate new values?

regards.
