How Electrical Interference can cripple your Control System
... When sensor signals are disturbed by an external power source you can expect measurement errors and process malfunctions. We will look at the mechanisms and principles behind electrical interference and point out some preventions and cures. Interfering sources include: nearby power cables, motors, t ...

... Surprising or not, they lose some or all of their inductance which then shunts incoming signals to ground causing the array to not work to its full potential. The most noticeable thing caused by this is the loss of front to back ratio. Secondly pattern distortion resulting in excess received noise. ...

... AC waveform usually is expressed as a RMS value. For instance, the electricity from a North American household electrical outlet is a low frequency (60 Hz) sine wave whose RMS voltage is about 120 volts. An unmodulated RF signal – also known as a continuous wave (CW) carrier – usually is a high-freq ...
