generate a tone
GenerateTone( n, magnitude, frequency, phase )
posint, number of samples to generate
realcons, magnitude of the signal
realcons, the frequency relative to the sampling frequency; with value 0 <= frequency < 1/2 (Nyquist sampling frequency)
realcons, the phase of the signal (0 <= phase < 2Pi)
container : Array, predefined Array for holding results
The GenerateTone(n, magnitude, frequency, phase ) command generates n samples for a tone (sinusoidal) signal with the indicated values for the magnitude, frequency and phase. The result is returned in an Array with datatype float.
If the container=c option is provided, then the results are put into c and c is returned. With this option, no additional memory is allocated to store the result. The container must be an Array of size n having datatype float.
The SignalProcessing[GenerateTone] command is thread-safe as of Maple 17.
For more information on thread safety, see index/threadsafe.
The container option can be used to put generated values into a predefined Array.
c ≔ Array⁡1..10,datatype=float8,order=C_order:
nSamples ≔ 200:
RelativeFrequency ≔ 0.02:
signal ≔ Array⁡GenerateTone⁡nSamples,1,RelativeFrequency,0
A plot of the signal vs the index position (note that this is not equal to time):
To plot the signal vs time, the sampling rate and signal frequency are required:
SamplingRate ≔ 1000:
The SignalProcessing[GenerateTone] command was introduced in Maple 17.
