This formula uses 1 Constants, 2 Variables
Constants Used
pi - Archimedes' constant Value Taken As 3.14159265358979323846264338327950288
Variables Used
Maximum 3db Bandwidth - (Measured in Hertz) - Maximum 3dB Bandwidth of the photodiode is the frequency at which the photodiode's response drops to -3 decibels (dB) or approximately 70.7% of its maximum response.
Transit Time - (Measured in Second) - Transit time is the duration for a charge carrier to move from where it's created in the photodetector's semiconductor material to where it's collected by the electrodes.
STEP 1: Convert Input(s) to Base Unit
Transit Time: 12.01 Second --> 12.01 Second No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
Bm = 1/(2*pi*ts) --> 1/(2*pi*12.01)
