b. What is the output signal amplitude in volts?
c. What is the...
For this question, yes, I am confused about the purpose of λ.
For all intents and purposes (and to prevent you from continuing the assumption I am a total idiot) I know that λ is wavelength, which is the distance between successive crests (high points) of any type of wave (ala period). Problem...
