public static void GenerateLogarithmicChirp(
	double amplitude,
	double startAngularFrequency,
	double endAngularFrequency,
	double initialPhase,
	Span<double> destination
)

Visual Basic

Public Shared Sub GenerateLogarithmicChirp ( 
	amplitude As Double,
	startAngularFrequency As Double,
	endAngularFrequency As Double,
	initialPhase As Double,
	destination As Span(Of Double)
)

C++/CLI

public:
static void GenerateLogarithmicChirp(
	double amplitude, 
	double startAngularFrequency, 
	double endAngularFrequency, 
	double initialPhase, 
	Span<double> destination
)

static member GenerateLogarithmicChirp : 
        amplitude : float * 
        startAngularFrequency : float * 
        endAngularFrequency : float * 
        initialPhase : float * 
        destination : Span<float> -> unit

Parameters

amplitude Double: The amplitude of the chirp.
startAngularFrequency Double: The starting angular frequency in radians per sample.
endAngularFrequency Double: The ending angular frequency in radians per sample.
initialPhase Double: The initial phase in radians.
destination Span<Double>: The destination span to write the generated signal.

Remarks

Generates a logarithmic chirp where the instantaneous frequency is:

ω[n] = ω₀(ω₁/ω₀)^(n/(N-1))

The phase is the cumulative sum of ω[n], and y[n] = A sin(φ[n]).

An empty destination is left unchanged. A single sample uses the initial phase.
