"The LM3915 is a monolithic integrated circuit that senses analog voltage levels and drives ten LEDs, LCDs or vacuum fluorescent displays, providing a logarithmic 3 dB/step analog display. "
What does the logarithmic 3 dB/step mean when a 10 led bargraph display is driven?
I mean, how can it be logarithmic and each step (LED) to display 3 db, isn't that linear?
Also, will the logarithmic scale variant be useful to make an S-meter for a radio, or the linear or the VU-meter scale variant of the chip family?
