An external audio signal is input to an input terminal which is connected to the first terminal of a first resistor. According to one embodiment, the PFC includes a pattern state machine and a pattern memory coupled to the pattern state machine. The sequence of layers in the reflective element is reversed in order such that the layers grown first with lowest surface roughness are exposed to the highest electric field strength, and the layer grown last, of highest roughness, are buried deep in the multilayer stack. The field programmable gate array applies a test signal to the display port timing controller, and controls the connecting signals applied from the display port transmitting part to the display port timing controller. A dynamic optical component positioned relative to the optical path to receive the intermediate real image is configured with one or more optical components which laterally translate a projected image without keystone distortion. A command is transmitted to the physical disk drive using the remapped file address range.
