Generate a Gaussian modulated sinusoidal pulse sampled at times t.

The input arguments are:

• t : vector of time values (in seconds) at which the pulse is evaluated.
• fc : center frequency in Hz (default 1000). Must be a non-negative real scalar.
• bw : fractional bandwidth (default 0.5). Must be a positive real scalar. The bandwidth is measured at the reference level given by bwr.
• bwr : reference level in dB (default -6). Must be a negative real scalar. The pulse’s envelope amplitude at the band edges is 10^(bwr/20) times the peak amplitude.

The output arguments are:

• yi : inphase (cosine) component of the pulse.
• yq : quadrature (sine) component of the pulse.
• ye : envelope of the pulse (same as sqrt (yi.^2 + yq.^2)).
