gauspuls

Syntax

p = gauspuls(t)

p = gauspuls(t, fc)

p = gauspuls(t, fc, bw)

p = gauspuls(t, fc, bw, bwr)

tc = gauspuls('cutoff', fc, bw, bwr, tpr)

Inputs

t

The times at which to generate the signal, or 'cutoff' to compute the time (> 0) at which the envelope falls to tpr dB.

Dimension: string | vector

fc

The center frequency. (default: 1000 Hz)

Dimension: scalar

bw

The fractional bandwidth. (default: 0.5)

This is the width of the Gaussian envelope at bwr dB, divided by fc. (default: 0.5)

Dimension: scalar

bwr

The fractional bandwidth reference. (default: -6)

Dimension: scalar

tpr

The trailing pulse reference. (default: -60)

For use when t = 'cutoff' to compute tc.

Dimension: scalar

Outputs

p

The gaussian-modulated pulse.

tc

The positive time at which the envelope falls to tpr dB.

Example

Plot a pulse with a 1200 Hz center frequency and a 0.4 fractional bandwidth, centered at t=3 ms on a 10 ms interval, sampled at 100 KHz.

t = [0:0.01:10] * 0.001;
p = gauspuls(t - 0.003, 1200, 0.4);
plot(t, p);
xlabel ('Time (ms)');
ylabel ('Amplitude');

Comments

gauspuls is commonly used as an input to pulstran.
