Web8 apr. 2015 · Temperature variation of attenuation and accuracy dictate the LSB value that can be achieved, given a requirement of monotonic variation. The lower the temperature variation and the higher the accuracy, the smaller the minimum attenuation step can be, like 0.5 dB in super RF CMOS attenuators. Webis larger for low attenuation values, i.e., low rain intensities, short links, and low frequencies. An important issue is the correct classification of each 15 min time interval as wet (or dry), i.e., characterized by the presence (or absence) of rainfall [8]. In this work, dry or wet identification is based on
