the battery (switch upwards). The LED can only be completely on or completely off; its instantaneous brightness is never actually between the two. However‚ if the switching rate equals or exceeds the response rate of our human eyes‚ instead of the binary on-off switching‚ our eyes act as “averagers” and the LED is perceived to have “dimmed”. This averaging is analogous to our eyes acting as an RC low-pass filter (see Figure 2). If the switching rate is periodic‚ then the time it takes for a full switching
