2023年4月28日 · I am just trying to understand why we use 2.2·τ when calculate the rise time. I can't find a derivation anywhere, I don't understand where this 2.2 comes from.

2023年4月14日 · Rise time has different definitions: Generally, it's the time taken by the output to reach 1. But it can be defined as from 10% to 90% for overdamped, and 5% to 95% for …

2022年3月8日 · Sometimes some manufacturers cheat a bit and say the rise time from 20% to 80% to make the time smaller, but when converted to 10% to 90% it is not so great. Some …

2018年7月24日 · "The rise time of a signal is the time difference between the crossing of the lower threshold and the crossing of the upper threshold for a positive- going edge. The X …

This is a term that should never be used without some qualification. Even a simple R-C filter has ambiguous rise time. Its step response is a exponential with no place being a clear "end". It's …

2021年10月30日 · The rise time would be something like 3 to 5 time constants depending on where you want to draw the line. \$\endgroup\$ – DKNguyen Commented Oct 30, 2021 at 5:57

2022年6月5日 · Increasing k moves the closed loop system closer to the point of instability. Increasing k increases percentage overshoot and reduces rise time (faster response). …

2023年10月20日 · Rise time is always a function of the load you're attaching; so, if whatever generates the squarish wave is already 50 Ω-matched, and you use 50 Ω cabling to an 50 Ω …

2017年9月26日 · Because then rise time at the output might depend on the pull-up (load) on the collector as much as on the BJT characteristics. It would help to know exactly what circuit …

2016年9月20日 · BW is bandwidth in GHz, and TR is rise-time in nanoseconds. This formula uses the 10/90 rise time. So if your rise time is 10 ns, then your BW is 0.35/10 = 0.035 GHz = 35 …
