Cost-Effective PLL Frequency Testing by Debismita Gupta is a document available to read on EtoBox.
What is Cost-Effective PLL Frequency Testing about?
1) The document discusses new approaches for measuring the output frequency of phase-locked loop (PLL) circuits used in multimedia devices on digital test systems. 2) One approach involves using a DSP-based algorithm to count signal transitions over a short period of time from acquired failure memory data, allowing faster testing than external counters while achieving sufficient accuracy. 3) Another approach applies Fourier analysis to the acquired signal shape to determine the base frequency in the freq
