Vg pulse.m

Veshtort-Griffin shaped pulses, generated from tables given in (http://dx.doi.org/10.1002/cphc.200400018). There are good reasons to believe (see Section 2.2 of the paper) that these are the best possible pulses within their design specifications and basis sets.

Syntax

    waveform=vg_pulse(pulse_name,npoints,duration)

Parameters

    pulse_name - a character string, one of the following: E0A, 
                 E0B, E100A, E100B, E200A, E200D, E200F, E300C,
                 E300F, E400B, E300A, E500A, E500B, E500C, E600A,
                 E600C, E600F, E800A, E800B, E1000B

    npoints    - number of discrete time intervals in the pulse

    duration   - duration of the pulse, seconds

Outputs

    waveform   - amplitude of the pulse at each interval (there
                 is no phase modulation), normalised to produce
                 a 90-degree pulse, rad/s

Examples

  >> t=linspace(0,1e-3,1000);
  >> w=vg_pulse('E800B',1000,1e-3);
  >> plot(t,w);
