Before FM demodulation we usually have a hard limiter. The hard limiter

Before FM demodulation we usually have a hard limiter. The hard limiter is made of two blocks, what are they? and what is the function of each? a) b) a) b) 2. (5 points) Although FM requires larger bandwidth than AM, FM is widely used due to different advantages. Mention two distinct advantages of FM over AM. 3. (5 points) Given the angle modulated signal XEM = 10 cos (2m x 10 +20 cos (10m-t)). for the message m(t) = -100 sin(10m t). Is XEM FM or PM? (why?) Find the value of k, i.e., kj or kp. O
