So I interpreted the formula wrong. The formula for a range of frequencies is Δt=1/Δf and not t=1/f. So the answer becomes Δt=1/(111MHz-80MHz) which then gives the answer 3.22*10^-8s when MHz are converted to Hz.
I'm not sure what else the duration of the pulse could be. I read somewhere that it is the time it takes from the the moment the pulse reaches half of its amplitude to the time it drops to the same level, but I'm not sure how that applies here or how I can use that information to solve the question.
So period is how long for a repetition to occur and frequency is how many repetitions per time unit. if units are Hz for frequency and seconds for period. Then you can say that T=1/f so that equation should give you the smallest duration (or period) of the pulse when you plug in the largest...
An electronic device is designed to amplify signals in the frequency range 80 MHz to 111 MHz. what is the smallest duration pulse in this frequency range that can be amplified without distortion?
