The Computer Analysis of Amplitude Limiter Signals

The results of calculation spectrum at entry and exit amplitude limiter under entry multifrequency and casual signals are given. Change of ratio signal-noise at exit limiter in comparison with those ratio at entry are determined.

As a result of computer analysis at environment MathCAD under ratio signal-noise ∆ = 10 dB and more can to make other conclusion:

- under noise in the form of sine function suppression «weak» noise helpful signals amount 6 dB;

- under noise in the form of multifrequency signals suppression every «weak» helpful signals amount not less 5 dB;

- under noise in the form of function rnd (x) at environment MathCAD ratio signal-noise at exit limiter in comparison with those ratio at entry improve 4 - 6 dB;

- by consider methodology can to investigate influence at amplitude limiter just as other noises.
