摘要： A receiver detector of a peripheral device for use in a computer system to detect whether a receiver is electrically coupled to a data port of the peripheral device includes a modulator, a high pass filter, and a demodulator. The modulator is configured to modulate a receiver detect signal at a frequency that is higher than a noise frequency, below which high amplitude noise can develop. The high pass filter is electrically coupled to the receiver detect signal and is configured to block frequencies of the receiver detect signal that are below the noise frequency and pass a filtered receiver detect signal. The demodulator is configured to demodulate the filtered receiver detect signal and produce a recovered receiver detect signal that is indicative of whether a receiver is electrically coupled to the data port.

摘要： A peripheral device includes a data port having high and low impedance terminations, a transmitter having a data signal generator and a receiver detector. The data signal generator is electrically coupled to the low impedance termination of the data port when in a low impedance operating mode, and to the high impedance termination when in a high impedance operating mode. The receiver detector includes a noise detector adapted to detect a presence or an absence of rail-to-rail noise at the data port when the transmitter is in the high impedance operating mode.
