Before revision: Harmonic generation If the incoming signal is a sine wave {Ein sin(ωt)}, (and taking only first-order terms), then the output can be written: Clearly, the harmonic terms will be worse at high input signal amplitudes, as they increase polynomially with the amplitude of ''E''in.
After revision: Harmonic generation If the incoming signal is a sine wave {Ein sin(ωt)}, (and taking only first-order terms), then the output can be written: Clearly, the harmonic terms will be worse at high input signal amplitudes, as they increase exponentially with the amplitude of ''E''in.
