Hi all,
I have a question, which one to use for class D audio amplifier ?
RC or LC and what the advantage and disadvantage of each one ?
Fc is 40Khz
I googled and come up inclusive

RC filters are lossy. Generally, you don't want to burn half your output power as heat; that defeats the purpose of choosing class D. :P
