# neurodsp.sim.cycles.sim_asine_cycle¶

neurodsp.sim.cycles.sim_asine_cycle(n_seconds, fs, rdsym)[source]

Simulate a cycle of an asymmetric sine wave.

Parameters
n_secondsfloat

Length of cycle window in seconds. Note that this is NOT the period of the cycle, but the length of the returned array that contains the cycle, which can be (and usually is) much shorter.

fsfloat

Sampling frequency of the cycle simulation.

rdsymfloat

Rise-decay symmetry of the cycle, as fraction of the period in the rise time, where: = 0.5 - symmetric (sine wave) < 0.5 - shorter rise, longer decay > 0.5 - longer rise, shorter decay

Returns
cycle1d array

Simulated asymmetric cycle.

Examples

Simulate a 2 Hz asymmetric sine cycle:

>>> cycle = sim_asine_cycle(n_seconds=0.5, fs=500, rdsym=0.75)
