... source’s output impedance. For example, cascading an array of 10 units consisting of EX10 speak ers produces an input impedance of 2000 ohms (20kOhms divided by 10). The source equipment should have an output impedance of 200 Ohms or less. This is also true when connecting EX10’s in parallel (loop o ...

... Just as with the BJT differential pair, we find that some DC offset voltage is present, even when the differential input signal is zero! The reason is likewise the same as with the BJT differential pair—our transistors and resistors can never be made perfectly identical! For example, we find that th ...

Ground loop (electricity)

In an electrical system, a ground loop is an equipment and wiring configuration which results in excessive unwanted current in a conductor connecting two points that are supposed to be at the same electric potential, often ground, but are actually at different potentials.Ground loops are a major cause of noise, hum, and interference in audio, video, and computer systems. They do not in themselves create an electric shock hazard, the inappropriate connections merely create a not necessarily very good instance of Electrical_bonding, which is explicitly required by safety regulations in certain circumstances. In any case the voltage difference between the ground terminals of each item of equipment is small. A severe risk of electric shock occurs when equipment grounds are improperly removed in an attempt to cure the problems thought to be caused by ground loops.
