3.8.      Interface Components:  The input device will interface with the

amplifier through a 1/8th inch stereo mini-plug. The amplifier will have a standard wall socket to connect with the test equipment because the amplifier’s main purpose is to simulate power quality problems from standard household power fixtures

3.9.Power Supply & Outlet:  A negative and positive voltage rail (90VDC) is required to power up the amplifier; this will be supplied by 4 AC to DC converters rated at 25VDC and 1.5 Amps, connected in series.

3.10. Design Cost:  The project cost should be $335.00 or less.  This will allow our device to be affordable to all manufactures as well as the general public. Other things were factored into the eventual pricing, like considerations for mass production and mass purchasing of components and work done to produce the prototype.
