PchipSinePulse

PchipSinePulse#

class PchipSinePulse(options)#

Bases: PartialPeriodicWaveform

PchipSinePulse generates sine wave pulses with PCHIP rise and fall transitions.

Creates sine wave pulses with smooth rise and fall transitions using Piecewise Cubic Hermite Interpolating Polynomial (PCHIP) interpolation. Provides smoother transitions than linear ramps. Inherits from PartialPeriodicWaveform.

Example1:

% Create a PCHIP sine pulse with rise and fall times
pulse = PchipSinePulse(amplitude = 2.0, frequency = 1000, ...
                       riseTime = 0.001, fallTime = 0.001);
pulse.plot();

Example2:

% Create a pulse with only rise time
pulse = PchipSinePulse(amplitude = 1.0, frequency = 500, riseTime = 0.002);
pulse.plot();
Constructor Summary
PchipSinePulse(options)#

Construct a PchipSinePulse object.

Parameters:

  • samplingRate (double, optional) – Sampling rate in Hz (default: [])

  • startTime (double, optional) – Start time in seconds (default: 0)

  • duration (double, optional) – Duration in seconds (default: [])

  • amplitude (double, optional) – Peak-to-peak amplitude (default: [])

  • offset (double, optional) – DC offset (default: 0)

  • frequency (double, optional) – Frequency in Hz (default: [])

  • phase (double, optional) – Initial phase in radians (default: 0)

  • riseTime (double, optional) – Rise transition time in seconds (default: 0)

  • fallTime (double, optional) – Fall transition time in seconds (default: 0)

Method Summary
TimeFunc()#

Get the time function for the PCHIP sine pulse.

Creates a function handle that generates sine wave pulse values with PCHIP-interpolated rise and fall transitions. Implements the abstract TimeFunc() method from Waveform.

Returns:

Function that takes time array and returns PCHIP sine pulse values

Return type:

function_handle
