Hello people...These problems been troubling me now for days...I need to find out if a signal has passed through three cascaded amplifiers, each with a 4 dB gain. What is the total gain? And how much was the signal amplified?
Also a signal has a wavelength of 1 Micrometer in air. How far can the front of the wave travel during 1000 periods? Can anyone please help me or give me advice as to where to locate this information.
