Only true for continuous RF sources. For transient signals you need at least Nyquist frequency.

- azalemeth 3y agoOr use the traditional "lock-in" amplifier technique of mixing with a known reference at the frequency mid-point of the range you care about? (That's how NMR spectrometers / MRI scanners worked for decades
- muffles 3y agoIsnt the lock-in amplifier technique used to improve the SNR ratio of a signal by filtering out noise at frequencies outside a specific range of interest? High-speed sampling would still be required to accurately measure transient signals.
- mhh__ 3y agoIn that sense isn't the bandwidth 0-Max anyway though?
