Unformatted text preview: analytically (and justify any assumptions). 4. Pulse Modulation (a) What is Pulse Amplitude Modulation? Provide a pictorial example. (b) What is Pulse Position Modulation? Provide a pictorial example. (c) What is Pulse Frequency Modulation? Provide a pictorial example. (d) What is Pulse Width Modulation? Provide a pictorial example. (e) Consider a full wave recti±ed AM signal r ( t ) = m ( t ) cos 2 πf c t where we assume m ( t ) ≥ ∀ t . Assuming the highest frequency content of m ( t ) is much less than f c , can r ( t ) be considered the approximate result of a pulse modulation method applied to m ( t ) ? If so, which one? 5.
