Module: tide.wavelets

Wavelet generators used for source design in FDTD propagation.

Functions

• ricker

ricker

Signature:

ricker(freq, length, dt, peak_time=None, dtype=None, device=None)

Parameters: - freq: dominant frequency in Hz, must be > 0 - length: number of samples, must be > 0 - dt: time sample interval in seconds, must be non-zero - peak_time: optional peak time, default is 1/freq - dtype/device: optional torch dtype and device

Returns: - torch.Tensor with shape [length]

Typical usage:

src = tide.ricker(8e8, length=1000, dt=4e-11).view(1, 1, -1)
