For your two tone signal, the PAPR is 3 dB, for just a four tone signal it is actually six dB. The amount that the input signal should be diminished to keep up linear amplification is named backoff, expressed in dB, and is often a little much more than the PAPR.

When this type of noise has an in the end deterministic trigger, it is commonly characterised inside a statistical way. Electromagnetic compatibility analyzes and styles this sort of sound, and develops circuit design and style ways acquiring minimal sensitivity to interferers.
