/blogs_/archives/b/thesignal/posts/logarithmic-potentiometersHave you ever tried to use a linear potentiometer (pot) as a volume control? Yikes! The volume jumps up much too rapidly. It requires a safe-cracker’s touch to adjust the volume to quiet listening levels. Thus the logarithmic potentiometer .

Also, most people prefer a finer control for lower volumes, so a perfect logarithmic pot isn&#39;t the best solution.</p> <img src="https://e2e.ti.com/aggbug?PostID=663588&AppID=864&AppType=Weblog&ContentType=0" width="1" height="1">
