![**Problem 4.22**
A laser diode has a maximum average output of 1 mW (0 dBm). The laser is to be amplitude-modulated with a signal \( x(t) \) that has a DC component of 0.2 and a periodic component of \( \pm 2.56 \). If the current-input to optical-output relationship is \( P(t) = i(t)/10 \), find the values of \( I_0 \) and \( m \) if the modulating current is \( i(t) = I_0 [1 + mx(t)] \).](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F50f8516f-ca69-4754-af99-d30dbf47eb66%2F0af24d1b-3380-4b1e-94d0-2c2c831dbd2b%2Fonyiiv2_processed.png&w=3840&q=75)
