Abstract:
A signal analyzer, comprising:a first processor receiving a first representation of an applied signal, and providing from the first representation at least two of a second representation, a third representation having a square relationship to the second representation, and a fourth representation having a logarithmic relationship to the second representation and the third representation; a filter receiving one of the second representations, the third representations and the fourth representations from the first processor selected according to a first input and reducing the variance of the received one of the representations; a second processor coupled to the filter and to a display processor, converting the received one of the second representation, third representation and fourth representation having reduced variance to at least two of a fifth representation, a sixth representation having a square relationship to the fifth representation, and a seventh representation having a logarithmic relationship to the fifth representation and the sixth representation and coupling to the display processor at least one of the fifth representation, the sixth representation, and the seventh representation according to a second input, wherein the first input and the second input are independently controlled.
