Quantization Noise - Washington University in St. Louis
classes.engineering.wustl.edu• To measure the Quantization noise, we should replace the 17 signal bins with the value of the leftmost signal bin (92) to approximate the quantization noise in the signal bins. The integral of this modified PSD from 0 to F s/2 is the noise power, σ2. The square root of this integral is …

iwooten.comThe service factor rating is the amount of output the motor can develop without causing harm to the motor. If a 5 HP motor has a service factor of 1.15 the motor can produce an output of 5.75 HP without harming the motor. The service factor could be seen as a safety measure which would allow the motor to produce extra power if it was needed.

www.pdhonline.comAn induction motor's speed is always less than synchronous speed and it drops off as load increases. For example, for 1800 rpm synchronous speed, an induction motor might have a full-load speed of 1748 rpm. On standard induction motors, the full-load speed is typically 96% to 99% of the no-load speed. This is known as slip.
