Gaussian-modulated sinusoidal RF pulse
Generate a Gaussian modulated sinusoidal pulse sampled at times t.
gauspuls(t, fc = 1000, bw = 0.5)
t |
Vector of time values at which the unit-amplitude Gaussian RF pulse is calculated. |
fc |
Center frequency of the Gaussian-modulated sinusoidal pulses, specified as a real positive scalar expressed in Hz. Default: 1000 |
bw |
Fractional bandwidth of the Gaussian-modulated sinusoidal pulses, specified as a real positive scalar. |
Inphase Gaussian-modulated sinusoidal pulse, returned as a vector of unit amplitude at the times indicated by the time vector t.
