تحقیق حاضر به بررسی درک دانشجویان از مزایا و معایب آزمون های کامپیوتری تافل و تاثیر جنسیت بر درک آنها پرداخته است. شرکت کنندگان در این تحقیق 100 نفرزبان آموز مرد و زن بودند که در آزمون کامپیوتری تافل در ایران شرکت کرده بودند. پرسشنامه یی که در مورد مزایا و معایب آزمون های کامپیوتری در مقایسه با آزمون های کاغذی توسط محقق تهیه شده بود جهت تکمیل به این افراد ارایه شد. داده های بدست آمده در این مطا...
15 صفحه اولJitter Test in Production for High Speed Serial Links
1. The new definitions of jitter In the last few years, more and more serial link standards adopted the concept of separating jitter into deterministic jitter (DJ), periodic jitter (PJ) and random jitter (RJ). The old concept of histogram based peak-to-peak jitter has been replaced by the concept of total jitter (TJ), which is associated with a certain bit-error-rate for the serial link (typica...
متن کاملPart 6 : Reference Clock Jitter and Data Jitter 1 Reference Clock Jitter and Data Jitter
Reference clock jitter sets the ultimate limit on the bit error ratio of a serial data system. The traditional techniques for quantifying jitter on clock signals don’t help system designers estimate the clock’s contribution to the total jitter defined at a bit error ratio. New techniques are being introduced to model how transmitters and receivers use reference clocks so that the system RJ and ...
متن کاملPeriodic Jitter Injection with Direct Time Synthesis by SPPTM ATE for SerDes Jitter Tolerance Test in Production
Controlled amount of jitter injection into high speed serial bit stream is required for SerDes jitter tolerance test. While jitter injection by Direct Time Synthesis can be a much more cost effective method than a combination of several instruments, it is not widely used yet. Considering its high potential in high volume production test cost reduction, we have studied the basics of the jitter i...
متن کاملEffects of Symbol Transition Density on Tracking and Acquisition Performance of the Data Transition Tracking Loop at Low Signal-to-Noise Ratios
Effects of the data transition variation on the performance of the digital data transition tracking loop (DTTL) symbol synchronizer are addressed for symbol signal-to-noise ratios and window sizes of interest. The data transition variation will affect the DTTL performance by introducing an additional timing jitter that results in additional receiver loss. Numerical and simulation results for bo...
