HI ALL
I agree with aabid baba. Both the components are different if one is modulator the other is amplifier..
Zulkarnain i will suggest you to go through Damian sirS’ post and it will be very convenient for you to differentiate between the two.. You may also go through the “component help” of both the components which is a basic thing you can do. It would give u an idea for sure.
Thanks and regards
