linear output to logarithmic output?

Is there a relatively simple way (I'm a simple kind of guy) to make a linearly scaled output produce the range (and sensitivity) of a logarithmic scaled output even just over a limited, delineated, linear span. Or are the scales mutually exclusive? Thanks.<p>[ July 09, 2004: Message edited by: perfe...

Yet another LED question

What makes a super bright LED different from a normal brightness LED? Thanks.

Re: Another LED question.

Dale Y. Thank you. Intellectually I have a rough understanding of Light Amplification by Stimulated Emission of Radiation but I was somewhat taken aback that my simple question could lead to a serious and learned discussion on photons phasing in LEDs. Decaying energy and all! <p>Mr Al's comment on a...

I know I started this thread but.....<p>"an LED and photons in phase"??????<p>I don't understood what that meant. It is stratospheric to landlubber me.<p>I fear I have rushed in where angels fear to tread.

Re: dB and hfe

Dale. Many, many, many moons ago when I attended technical college in a very low level course of study I asked the slide rule teacher what the Log Log scale on my, given as a gift, case and all, Pickett slide rule was for. "Who knows?" was the answer. "Just concentrate on the front bottom scales." s...

Re: dB and hfe

So, in looking at the gain for a transistor hfe is used but in looking at the output signal for an op-amp dB would be used regardless of the strength of the input signal? Thank you Chris.<p>[ July 03, 2004: Message edited by: perfectbite ]</p>

dB and hfe

Can dB and hfe be rendered as similar or interrelated measurements under differing conditions or are they entirely distinct from each other? Thanks.<p>[ July 03, 2004: Message edited by: perfectbite ]</p>

Another LED question.

Will non powered LEDs give voltage or current when exposed to a light source? If so, in what quantities? Thank you.

Re: Temp. circuit on page 66 of July N&V

Thank you Haklesup and Ron H. I've reached the edge of calculus in electric theory, Phew! And understood it's significance. Double Phew! <p>Mike, I'm glad you got the answer with the schematic so that I could ask another of my dumb, some would say inane, questions. Thank you for asking the question....
