The resultant normalized frequency has units of half-cycles/sample or equivalently cycles per 2 samples. Sometimes, the unnormalized frequency is represented in units of radians/second (angular frequency), and denoted by When is normalized by the sample-rate (samples/sec), the resulting units are radians/sample.ometimes, the unnormalized frequency is represented in units of radians/second (angular frequency), and denoted by When is normalized by the sample-rate (samples/sec), the resulting units are radians/sample.

The same question for a right hilar soft tissue opacity measuring approximately 2.2 x 1.9 x 1.4 cm and a wavy, tubular appearing opacity in the right upper lobe measuring approximately 2.6 x 0.8 cm.Also what does âmild posterior atelectasisâ mean? I really do appreciate any info you can give me.here is a 3.8 x 2.7 x 2.6 cm mass in the subcarinal region. This probably represents a conglomeration of enlarged lymph nodes. There is a right hilar soft tissue opacity measuring approximately 2.2 x 1.9 x 1.4 cm.
