116.1c Frequency Modulation (FM) ON15 P41 Q11 | A2 Communication | Cambridge A Level Physics

[@amirahossain6602]

I love your videos.You guys are the only reason as to why I will pass my A levels exam this October session. :')

[@hiqmahmaliq467]

Your videos really helps.. Tq!!! 🥰 Really appreciate it

[@dylanscottmufandaedza8146]

whats the formulae for the frequency deviation

[@ETphysics]

They would usually give a value for freq deviation, cuz it's too advanced to calculate at A Level 😅 (cough Electrical engineering cough)

[@dylanscottmufandaedza8146]

To find the change in frequency of the carrier wave, how do you know what frequency to multiply with ?

[@markduenas0927]

Hello! For the question part (ii), how do I know that I need to use the information signal?

[@ETphysics]

Hmmm what affects/controls the frequency of the modulated carrier wave?
