Average Power from FM radio transmitters - RF Cafe Forums

The original RF Cafe Forums were shut down in late 2012 due to maintenance issues - primarily having to spend time purging garbage posts from the board. At some point I might start the RF Cafe Forums again if the phpBB software gets better at filtering spam.

Below are the old forum threads, including responses to the original posts.

Dear All,
I was wondering how, in general terms, one might calculate the average power radiated from an FM radio broadcast transmitter. Now, most transmitters list their ERP (which is the peak power times the antenna gain), but I need to know what the average transmitted power is?

Bearing in mind that the FM radio band (88-108 MHz) contain many different broadcast channels within its 20 MHz bandwidth. So, the energy is probably not distributed eavenly across the band. How will this affect the average power calculation?

Suggestions will be gratefully appreciated.
Happy New Year to any of our Chinese colleagues who might be reading this.

Best Wishes
RF Burns

RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer. The World Wide Web (Internet) was largely an unknown entity at the time and bandwidth was a scarce commodity. Dial-up modems blazed along at 14.4 kbps while typing up your telephone line, and a nice lady's voice announced "You've Got Mail" when a new message arrived...
