ground loop - Circuitos electrónicos

The VERONICA transmitter is a very stable, powerful, and high quality FM emitter. Thanks to a PLL, the output frequency is controlled with DIP switches. Output power is approximatively 1W with a single regulated 13.8v supply ! (see specifications) Features : * High RF output power : 1W * Full 87.5-108MHz range (100KHz increment). * Very stable output frequency : Crystal reference & Phase Locked Loop. * Professional input bandwith (fully RDS compatible ) * No complex tuning needed. * H.......

These days many more audio-visual devices in the home are connected together. This is especially the case with the TV, which may be connected to a DVD player, a hard disk recorder, a surround-sound receiver and often a PC as well. This often creates a problem when earth loops are created in the shielding of the video cables, which may cause hum and other interference. The surround-sound receiver contains a tuner that takes its signal from a central aerial distribution system........
