The limiters cut off the top and bottom of the wave and make them all the same height. so the discriminator will give u a clean voice with no static. The static forms on the top and bottom of the carrier.

Since there is no Amplitude modulation present in an FM signal, the FM amplitude may be amplified to the point of saturation of the amplifier chain. That is the maximum possible amplitude gain to the point of transient intermodulation distortion of the amplifier stage -- which would start to add unwanted frequency components into the signal. Basically, that is what limiting is.

The incoming signal is given huge amplification and then clipped by the limiter. The limiter removes any amplitude modulation due to fading or noise.
