QUESTION 3 A laser diode has a threshold current of 4 mA and a slope in its linear region equal to 3 mW/mA. The input information sig is zero at the minimum of the waveform). (a) Write the equation for the total output power. (b) Write the equation for the total input current to the laser diode. 0 points Save Answer input information signal is a sinusoid having peak current of 3 mA and a frequency of 1000 Hz. The modulation is 100% (that is the power
