Thusly, the object of this invention is to eliminate the ground loop problem. Further, the object of this invention is to greatly reduce the distortion of any electronic device by eliminating the ground loop problem. The invention that achieved this elimination of the ground loop problem is a unique circuit that consists of diodes, piezoelectric crystals, neon bulbs, or transient surge suppressors. The advantage of the inventor&#39;s system is that distortion, the power consumption, and the unwanted heating of the device to which the invention is connected, is greatly reduced.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT 
     Reference is now made to the figures. The figures in all like parts are represented by like reference numerals. FIG. 1 shows one of the inventor&#39;s embodiment for elimination of the ground loop problem. In this embodiment piezoelectric crystals 90 are attached in parallel with each of the capacitors 92 in the simple transistor amplifier. However, the principle of attaching piezoelectric crystals in parallel with capacitors can be used in any amplifier or electronic device. In these devices, the piezoelectric crystals attached in parallel to capacitors will help eliminate the ground loop problem. FIG. 2 and 3 show that the piezoelectric crystals can be replaced with a diodes 94 and 95 attach anode to anode as in FIG. 2 or cathode to cathode as in FIG. 3. The applicant has found that these diodes 94 and 95 attach anode to anode and cathode to cathode when attached in parallel across all the capacitors in an amplifier or electronic device is the best method for elimination of the ground loop problem. The applicant has found that piezoelectric crystals with a resonate frequency of 400 kilohertz or less, which are attached to all the capacitors in the electronic device or amplifier works almost as well as the diodes attached in parallel across all the capacitors. As shown in FIG. 4 neon bulbs 96 can also be used. These neon bulbs 96 are as the diodes 94 and 95 and the piezoelectric crystals 90, attached in parallel across the capacitor in an amplifier or electronic device. The neon bulbs work better then the piezoelectric crystals in eliminating ground loop distortion, but not nearly as well as the diodes. 
     However, due to the complexity of putting the piezoelectric crystals, neon bulbs or diodes across all of the capacitors the applicant has produce several other embodiments that are power supplies which reduce or eliminate the ground loop problem. FIG. 5 and FIG. 6 shows the ways of modifying a half wave rectifier power supply. Basically with this design a diode is placed across the output lines beyond the regular half wave rectifier diode. In, FIG. 5 diode 32 is the diode of the regular half wave of the rectifier. Diode 36 is then put across the output lines, with its positive end hooked to the positive output 37 and its negative end hooked to the negative output 38 in the circuit. Diode 36 is hooked across the output lines with it positive end to the positive end of Diode 32. An electrolytic capacitor is hooked to the two outputs, 37 and 38 of the power supply. In FIG. 6, diode 42, which is he diode of a regular half wave rectifier is placed in the circuit in the opposites direction of diode 32. In this case, diode 46 is placed in the circuit to eliminate the ground loop problem and is placed across the output lines 47 and 48 with its negative end attached to the negative end of diode 42. The positive end of diode 46 is attached to the positive output 48 and the negative end is attached to the negative output 47. Capacitor 44 is attached across the two outputs 47 and 48. By attaching this extra diode, these power supplies will eliminate the ground loop problem in the electronic device.

The power supply will also cut down on distortion in digital circuits that are attached to it and it also increases the speed in which digital circuits can be switch as well as lowering the power consumption of most circuits. Of the full wave bridge rectifier circuits, this circuit does the best eliminating distortion and allows video, audio and digital circuits to work more efficiently.
