(a) Modified pulse scheme with an excitatory pulse Ie = 3.0 mA of pulse width t1 = 7 ns, for 4-binary digit pattern 1010 with pulse period (Δt) of 4 ns and pulse width (τ) of 3 ns. The pulse gap of δ = 5 ns between Ie and 4-binary digit patterns is shown with the grey box. (b) Magnetization dynamics of Mx component and (c) corresponding spectral characteristic FFT plot. (d–f) Similar plots of input pattern, magnetization dynamics and FFT for 0101 pulse pattern. Guide line in FFT plots show the amplitude value at 9.0 GHz.
