93K views · 1.2K reactions | This example demonstrates a frequency doubler, where a 24.5 MHz input signal is processed through a nonlinear transistor-based circuit to produce an output at double the input frequency. The design exploits harmonic generation and filtering to isolate the second harmonic, effectively doubling the frequency of the input signal. #ElectronicsEducation #electronicsrd #frequencydoubler | Electronics Education | Facebook
