Spoiler summary: The quarter-wave stub resonant frequency, when built in FR4, is about: f[GHz] = 1.5/Len[inches] or f[GHz] = 3.8/Len[cm]. Remember: before you start using rules of thumb, be sure to ...
A 10-MHz sinusoidal carrier wave of amplitude 10 mV is modulated by a 5-kHz sinusoidal audio signal wave of amplitude 6 mV. Find (a) the frequency components of the resultant modulated wave and (b) ...
Modern oscilloscopes capture, view, measure, and analyze complex RF signals in the time, frequency, and modulation domains. Time-domain analysis, the original oscilloscope function, allows users to ...
