Fuzzy Logic for Embedded Microcontrollers

Figure l--Traditional sets are simply defined by their endpoints. Fuzzy sets add a second dimension to express fhe
degree of truth (on the y-axis), which allows sets to be defined with gradual boundaries between false and true.

Fuzzy logic doesn’t necessarily need lots of horsepower. Many embedded applications that use more traditional control schemes can benefit from the use of fuzzy logic. Back in 1995, Jim Sibigtroth explained how to keep things simple and speedy. In Circuit Cellar … Continue reading

Fundamentals of I/Q Signals

Figure 1: A mixer works by multiplying two sine signals of frequencies FRF and FLO. Thanks to the well-known trigonometric formula reminded here, the product is the sum of two other sine signals, respectively, at frequencies FRF + FLO and FRF – FLO.

When talking about frequency mixers, “I/Q” has nothing to do with an intelligence quotient. As Robert explains, the “I” stands for “in phase” and the “Q” is for “in quadrature.” In this article, he introduces you to the fundamentals of … Continue reading
