This application note describes the procedure used within the Timing and Synchronization (TSD) division of IDT to analyze the PSNR for its devices. Power supply noise rejection (PSNR) is a measurement of how well a circuit rejects noise from various frequencies which are coupled into the power supply. In actual high speed analog and digital circuitry, the power supply pins are vulnerable to random noise Most customer designs use linear voltage regulators or switching voltage regulators as the power supply for ICs. Linear regulators will almost always get input voltage from a switching DC/DC converter. Therefore, power supply noises in a customer board typically come from the switching noise of the power supply and coupling from other high-frequency sections of the circuit board. Many of the problems facing PCB designers today are related to power supply noise. There are guidelines that can be used to solve simple issue. For more complex issues, a better understanding and consideration of all the parameters will be required to provide a clean solution. For this reason, it is essential to understand the PSNR of the clock devices. This can assist in designing the correct bypassing and decoupling for the system.

噪声标签生成和重新标记 在给定噪声率的情况下为数据集生成噪声标签，并使用重新标记算法对这些噪声标签进行重新标记 f1.test.py为all_tickets.csv数据集生成嘈杂的标签，使用“ body”作为特征，使用“ urgency”和“ ticket_type”作为预测标签。 我们假设'紧急'标签可能有一些嘈杂的标签，所以我们在'紧急'上添加了噪音。我们将48000数据拆分为火车数据集，将左侧的数据拆分为测试数据。在为'紧急'生成嘈杂标签's'之后，我们将' body。，'ticket_type'和's'到train_data.csv。在category.py中，我们生成重新标记的标签'relabel'并将其写入relabel.csv文件。除了门票数据集之外，我们还测试了其他数据集。 资料集 文件 结果文件夹 all_tickets.csv test.py 票 情绪训练 tes
