2020年9月22日 · Using your 1/5 rule of thumb the adequate sampling rate is 70*5 = 350MHz. That is, the sampled signal should be 1/5 the sampling rate. Oscilloscopes tend to want higher sampling rates for the same reason we want HD then 4k then 8k videos - higher resolution so that the waveform doesn't suck when you zoom in \$\endgroup\$ –

2020年4月27日 · Sampling rate (as defined by here is related to the process of constructing a digital representation of an analogue value: - T is the the period between samples hence the sampling rate is 1/T. Date rate: Say for instance each point on the above waveform was sampled with a 16 bit ADC, at a rate of 1,000 times per second.

2021年4月25日 · Audio Sample Rate is grayed out and wont let me change it. I have tried uninstalling audio drivers and restarting the computer. I have also tried to reinstall the device specifically but it still wont work.

2023年8月13日 · If you need to sample frequencies up to 10 kHz, you need a sampling rate above double that, so more than 20 kHz. This is the Nyquist sampling theorem. If you sample at 20 kHz, the sampled data must not have any frequencies above 10 kHz. So you need a filter that passes everything below 10 kHz and nothing above 10 kHz.

2018年7月6日 · E.g. if you have an UART interface with 115200baud you need a sampling rate of roughly 231kHz do detect all transitions. Now of course the higher your sampling rate the better is your chance to correct for errors on the transmition line. If you're sampling an analogue signal you're in charge of coming up with the corresponding specification.

2019年3月28日 · I work with audio using an external audio usb interface running at 44.1k. Windows is changing it to 48k for some reason... so I have to set Windows sampling rate to 44.1k to match my external audio usb interface (scarlett 18i20). But I cannot access any p

2017年6月16日 · That depends on the source of the measured signal. Some time is required to charge the ADC input capacitance, so if your signal circuit can't sink / source enough current the sampling time will need to be longer. The longer the sampling time, the slower the ADC sample rate will be. On some STM micros you can use built-in opamps as the input ...

Now the device has a sampling rate of 1kHz, i.e it takes 1000 samples of voltage per second. And when I set the baud rates and the rest by using HyperTerminal and connect to the port, I can see 4 voltage readings per second as incoming lines. My questions are: 1-) The analog sampling rate of the device was 1kHz, but I receive 4Hz per second.

sampling rate [in Samples/s] capture rate [in waveforms/s] record length [in pts/channel] My question is: How are these specifications related? Take for example the following comparison table from the company Siglent: All these scopes have a sampling rate of 1GSamples/s, meaning they can take 1 billion measurements every second.

2024年9月16日 · Look for the key value related to the sampling rate on the right (for example, ChannelConfig or Format) and modify its value manually. Save and restart the system. Disclaimer: Generally, modifying registry subkeys or work group is intended for advanced users, administrators, and IT Professionals. It can help fix some problems, however, serious ...
