Because of the high maintenance needed to monitor and filter spammers from the RF Cafe Forums, I decided that it would
be best to just archive the pages to make all the good information posted in the past available for review. It is unfortunate
that the scumbags of the world ruin an otherwise useful venue for people wanting to exchanged useful ideas and views.
It seems that the more formal social media like Facebook pretty much dominate this kind of venue anymore anyway, so if
you would like to post something on RF Cafe's
Facebook page, please do.
Below are all of the forum threads, including all the responses to the original posts. sma100 Post subject: ALC (automatic level control) Unread postPosted: Tue Mar 16, 2004 1:28 am Offline Lieutenant Joined: Tue Mar 16, 2004 1:26 am Posts: 1 Hello, Anybody know how I can design an ALC circuit with a pin attenuator and a crystal detector. Freq range (DC - 500 MHz). Thanks.

These and others can be found on the App Notes page right here on RF Cafe. Good luck to you. - Kirt B. :mrgreen: Top Profile Puck Post subject: Unread postPosted: Wed May 05, 2004 3:30 pm Think about the time response and you will get it. With properly made ALC you can get 6dB or more s/n ratio for voice. Video is different. Generally it provides dynamic range compression. Posted 11/12/2012 | ||||||
