NE555时序电路计算器

555时序电路是一种常用的集成电路，用于产生各种脉冲波形和定时功能。以下是一个简单的555定时器的计算器，可以帮助您计算所需的电路元件值和输出波形的参数。

Input parameters:R1 (ohm); R2(ohm); C(F)

Output parameters:Duty cycle(%), High time(s),Low time(s), frequency(Hz)

Calculation formula:
TH (High time s) = 0.693 * (R1 + R2) * C
TL (Low time s) = 0.693 * R2 * C
Frequency(Output frequency) = 1.44 / ((R1 + R2 + R2) * C)
DCP(Duty cycle%) = (T(h) / (T(h) + T(l))) * 100
