Analog remote control signal's threshold voltage, length and delay
Why is there such a delay, between Hi and Lo, etc? because the various filters will only settle with certain bandwidths. A single RC filter, of time constant 159 microseconds, has bandwidth of 1KHz == 1/(2 * PI * 159uS), Each Tau of settling brings the output voltage 67% closer to the final/steady_state value.
I use Signal Wave Explore to demonstrate this



In this example the "system" is just a R+C low pass filter, with bandwidth of 2MHz. The time constant is (1 / 6.28) * 1/2MHz = 0.159 * 500 nanoseconds = 40 nanoseconds.

The time-per-division is 100 nanoseconds; thus in 40% (40nanosecond) of one horizontal division, the output waveform (the lower waveform) moves another 67% closer to final steady-state value.
