How To Connect Z-5500 To Laptop For Digital Signal

The digitization of the analog signal can solve the problem the simulation system, but can also add the following advantages.In the digital recording system, due to the record in the form of Dell Studio XPS 1640 battery the signal is a binary digital, digital circuits task is to determine "0" and "1" two signals, so that the anti-jamming capability of the digital circuit to be greatly enhanced. At the same time, no direct relationship with the signal to noise ratio of the recording media and playback signal to noise ratio, so that compared with the analog recording system can be much more lenient requirements for recording media,hp ProBook 6540b battery digital systems can use cheap materials as the recording media;



In digital systems only "0" and a "two level state of the signal in the process of recording and playback as long as they" 0 "," 1 "signal sufficient level difference between the digital circuit will be able to easily identify and isolate. In other words, when a group of representatives of low "0" signal level even if the magnitude of the different at the same time on behalf of a group of high level "1" signal level is uneven Dell W953G battery situation exists, as long as 0 "," 1 "signal between the electrical adjustment large enough, digital circuit through the limiter circuit processing can correctly distinguish between" 0 "and" 1 "signal, which indicates a strong anti-jamming capability of the digital circuit ;



Digital systems, sampling frequency, quantization bits (these two concepts are described later) to determine the performance limit of the circuit is determined, the laptop battery is not easy to change, indicating that the digital recording system performance re- now is very reliable, but the analog recording system, due to the presence of many factors of instability, reproducibility performance is unstable, Acer TravelMate 8572T battery unreliable. Therefore, the technical performance of the technical performance of the digital system than the analog system to be much higher;this conversion usually analog-to-digital converter ADC (A / D) The Executive.
