If you need to generate a radio frequency electrical signal, you will make some form of electronic oscillator. We’ll probably all be used to oscillators using transistors, tubes, logic gates or a host ...
Narrow-band VLF transmitter waves originate from the powerful ground-based VLF transmitters for submarine communications, which are typically over the frequency range of 10–30 kHz. VLF transmitter ...
The Global Ionospheric Flare Detection System (GIFDS) of the DLR consists of a ground-based network of VLF receivers (Perseus SDR - Software Defined Radio), which provides amplitude and phase ...
While everyone is focused on RF signals in the gigahertz-plus range, it’s important to remember that the other end of the electromagnetic spectrum also has its uses. However, signals in ...
