Hello List members,
Is there a formula for calculating tuned input circuit Q. I see a chart =
in Bill Orr,s Handbook for various input impedances with Q,s of 2-3. Im =
probably missing something here. How would you calculate for a tuned =
input Q of 5. Im trying to learn so if its a dumb question I apologize =
for my lack of experience. Is it roughly Rin/xc1? Im curious as how to =
arrive at the values for a tuned input pi net for a given Q.
73,s Jeff
