How can we design this kind of circuit? The sensor doesn’t seem
There are generally two reasons for oscilloscope waveform jitter. One is that the signal is not synchronized, which is a problem with the oscilloscope trigger setting. The other is that the signal its
Signal integrity is the main criterion for measuring signal quality with an oscilloscope, especially when we need to observe small signals or slight changes in large signals, signal integrity becomes
I have seen similar millimeter wave human body sensing modules on Taobao before. The cheapest one is only a dozen yuan.
I didn't find any information about this XenD101 module, but I guess it won't be
