# scipy.signal.gausspulse

`scipy.signal.``gausspulse`(t, fc=1000, bw=0.5, bwr=-6, tpr=-60, retquad=False, retenv=False)

  Return a gaussian modulated sinusoid: exp(-a t^2) exp(1j*2*pi*fc*t).

  If retquad is True, then return the real and imaginary parts (in-phase and quadrature). If retenv is True, then return the envelope (unmodulated signal). Otherwise, return the real part of the modulated sinusoid.

  Parameters : | t : ndarray, or the string ‘cutoff’ Input array. fc : int, optional Center frequency (Hz). Default is 1000. bw : float, optional Fractional bandwidth in frequency domain of pulse (Hz). Default is 0.5. bwr: float, optional : Reference level at which fractional bandwidth is calculated (dB). Default is -6. tpr : float, optional If t is ‘cutoff’, then the function returns the cutoff time for when the pulse amplitude falls below tpr (in dB). Default is -60. retquad : bool, optional If True, return the quadrature (imaginary) as well as the real part of the signal. Default is False. retenv : bool, optional If True, return the envelope of the signal. Default is False.
