2 Mirror Frequency Filter 2.1 Mirror Frequency In radio reception using heterodyning in the tuning process, the mirror frequency is an undesired input frequency that is capable of producing the same intermediate frequency (IF) that the desired input frequency produces. It is a potential source of interference to proper reception.

Variable Frequency Drives and Energy Savings It's more than just fan and pump applications by: Stephen Prachyl . An AC variable frequency drive, used with an AC motor will operate at about 0.95 power factor which is typically 5 to 10 percent better than an across-the-line motor. Furthermore, there is at least one Active Front End (AFE) AC .
