Added new engineering tool: Square wave generator using IC 555 calculator

08/01/2024

Square wave generator using IC 555 calculator allows you to easily determine pulse frequency and othe parameters of a circuit.

A square pulse generator built on the basis of the popular 555 microcircuit works as a multivibrator i.e. in self-oscillating mode. This is a mode in which impulses arise themselves, without any external influences.

To calculate the pulse frequency, you can use the formula:

f = 1 / (0.693 * C1 * (R1 + 2 * R2)),
t1 = 0.693 * (R1 + R2) * C1,
t2 = 0.693 * R2 * C1
