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.
