The process of backtracing involves finding the input signal to an analog circuit, from knowledge of its input-output behavior and the desired output signal. While previous approaches rely on the transformation of nodal equations of the circuit to accomplish backtrace, the proposed approach derives ...
Digital communication is a new industry in the communications industry.Compared with the traditional analog communications,it has a strong anti-interference ability,the communication quality is not influenced by distance,the signal is easy to modulate,the secrecy is high,can discover and control errors...
The analog switch is mainly to complete the signal switching function in the signal chain. The switching mode of the MOS tube is adopted to realize th...
"Modem" is short for Modulator and Demodulator, originally referring to a device that converts digital signals into analog signals that can be transmitted over telephone lines. However, in the computer field, "Modem mode" usually means that the USB device simulates a virtual serial port (COM ...
