An ADC chip, which is an abbreviation of Analog-to-Digital Converter, is an integrated circuit that converts an Analog signal into a digital signal. ADC chips are widely used in various electronic devices, such as audio devices, communication devices, measurement instruments, etc., for converting analog signals into digital signals for digital signal processing and storage. The working principle of the ADC chip is that continuously-changing analog signals are converted into discrete digital signals through sampling and quantization processing. The sampling is to sample the analog signal at a certain time interval and discretize the continuous analog signal. Quantization is the discretization of the analog signal amplitude at each sample point into a number of discrete levels, typically using a binary representation. The ADC chip completes sampling and quantization processes through internal circuits and algorithms and outputs corresponding digital signals. The performance indexes of the ADC chip comprise resolution, sampling rate, signal to noise ratio, distortion degree and the like. Resolution indicates how many discrete levels the ADC chip can divide the analog signal into, typically expressed in terms of bits, such as 8 bits, 10 bits, 12 bits, etc. The sampling rate represents how many samples per second the ADC chip is capable of taking, typically expressed in hertz (Hz). The signal-to-noise ratio represents the ratio of the effective signal to the noise signal in the digital signal output by the ADC chip, and the degree of distortion represents the degree of error between the digital signal output by the ADC chip and the original analog signal. Common ADC chips are of many kinds and specifications, and suitable chips can be selected according to the specific application requirements.
LOG, a term in computer technology, refers to a file or data that records various events and information generated during the operation of a system. The log has important functions in a computer system and is used for fault detection, performance analysis, security audit and other aspects.
