Here was a little pocket ‘scope from China with an internal battery, a proper probe, and most importantly, a claimed 20MHz bandwidth. Best of all, it could be had for a relatively paltry £36 ($47)!

In decades past that usually meant a relatively modest instrument, maybe a 20MHz bandwidth and dual trace if you were lucky. Higher spec devices were eye-wateringly expensive monsters, not for the ...

FM broadcast standards range from 88 MHz to 108 MHz. That means the maximum bandwidth is 20 MHz. You can think about that like the maximum width of the highway, rather than how many lanes it has.

In this paper, we present a flexible ring oscillator IP designed for a 40nm CMOS technology, whose oscillation frequency can be chosen from 200kHz to 20MHz. It was developed using a new design ...
