When talking about oscilloscopes, one cannot help but recall the time spent testing at Samsung.The first version of the product’s PCB was followed by time spent in the lab, racing against product cycles, with continuous validation and testing during that period.It has been a long time since I last tested; I feel a bit nostalgic … Read more
Before learning how to use an oscilloscope to reduce noise, let’s first understand how noise in oscilloscopes arises. Many people who have just transitioned from analog oscilloscopes to digital oscilloscopes may complain that the waveforms measured by their new oscilloscope are not as clear as those from their old analog oscilloscope, even doubting whether their … Read more
Digital Signal Processing (DSP) is applied to the collected time-domain signals to obtain their frequency-domain results. When a signal is transformed from the time domain to the frequency domain, there are specific DSP terminologies, and these terms have important mathematical relationships with each other. Are you clear about them? The following are the DSP terminologies. … Read more
