This control can be achieved using a frequency converter. As the name suggests, a frequency converter changes the frequency of the alternating current and voltage. A frequency converter con-sists of three parts. Regular 50 Hz 3-phase current is fed in to the rectifier part, which converts it to direct current. The DC voltage

1. Spectrometer Frequency [sfrq]: It is called a “1-PULSE” experiment because one radio frequency (Rf) pulse (pw) is applied per cycle. The Rf pulse excites the nuclei, which then emit Rf during the acquisition time, giving rise to an NMR signal in the form of an exponentially decaying sine wave, termed free-induction decay (FID).

RF Field Fingerprint Sensors • A low radio frequency (RF) signal is injected into the finger, then read by the sensor array on silicon which act like receiver antennas. • The signal strength at each antenna (or pixel) depends on the distance between the skin at that point and the sensor. This is how the image of the fingerprint is produced.
