ConstantWave

ConstantWave#

class ConstantWave(options)#

Bases: PeriodicWaveform, ConstantTop

ConstantWave generates a constant (DC) waveform.

Creates a waveform with a constant amplitude value over the specified duration. Inherits from PeriodicWaveform and ConstantTop for periodic behavior and constant amplitude properties.

Example1:

% Basic constant waveform
const = ConstantWave(amplitude = 5.0, duration = 0.01);
const.plot();

Example2:

% Constant waveform with offset
const = ConstantWave(amplitude = 2.0, offset = 1.0, duration = 0.005);
const.plot();
Constructor Summary
ConstantWave(options)#

Construct a ConstantWave 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: [])

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

Method Summary
TimeFunc()#

Get the time function for the constant waveform.

Returns a function handle that generates a constant value over the specified duration, zero outside the duration. Implements the abstract TimeFunc() method from Waveform.

Returns:

Function that takes time array and returns constant values

Return type:

function_handle

Example:

const = ConstantWave(amplitude = 2.0, duration = 0.01);
func = const.TimeFunc();
t = 0:0.001:0.02;
y = func(t);
