How to generate a sine wave using DSP?
sine = dsp.SineWave creates a sine wave object that generates a real-valued sinusoid with an amplitude of 1, a frequency of 100 Hz, and a phase offset of 0. By default, the sine wave object generates only one sample. sine = dsp.SineWave (Name,Value) creates a sine wave object with each specified property set to the specified value.
How to generate a discrete time sine wave?
To generate a discrete-time sinusoidal signal: 1 Create the dsp.SineWave object and set its properties. 2 Call the object with arguments, as if it were a function. More
What is the data type of a sine wave?
Data type of the sine wave output, specified as ‘double’ , ‘single’, or ‘Custom’. Output word and fraction lengths, specified as an autosigned numeric type with a word length of 16. This property applies only when you set the Method property to ‘Table lookup’ and the OutputDataType property to ‘Custom’.
How to generate fixed point sine wave Simulink?
To generate fixed-point sinusoids, you must set the Computation method to Table lookup. Optimizes the table of sine values for Speed or Memory.
How to create a discrete sine wave filter?
Bandpass filter a discrete-time sine wave signal which consists of three sinusoids at frequencies, 1 kHz, 10 kHz, and 15 kHz. Design an FIR Equiripple bandpass filter by first creating a bandpass filter design specifications object, and then designing a filter using these specifications.
Why are sinusoids important in the analysis of filters?
Another reason sinusoids are important is that they are eigenfunctions of linear systems (which we’ll say more about in § 4.1.4 ). This means that they are important in the analysis of filters such as reverberators, equalizers, certain (but not all) “audio effects”, etc.
How are sinusoids similar to monochromatic laser light?
Sinusoidal signals are analogous to monochromatic laser light. You might have seen “speckle” associated with laser light, caused by destructive interference of multiple reflections of the light beam. In a room, the same thing happens with sinusoidal sound.
