RESPITE: The CASA Toolkit Page: Documentation: Block Library Index:SineWave


SineWave is a periodic signal generator block that generates a sine wave. There are 5 controlling parameters: SAMPLE_RATE, DURARION, FREQ, AMP, and initial PHASE.

SAMPLE_RATE is in units of samples per second, DURATION is measured in seconds, FREQ in cycles per second and PHASE in radians. The sine wave has maximum and minimum values of +AMP and -AMP.

Inputs Meaning Sample 1-D frame $\ge$2-D frame
No inputs

Outputs Meaning
out1 generated signal

Parameters Type Default Meaning
SAMPLE_RATE Float - Number of samples per second
DURATION Float - Duration in seconds of signal to generate
FREQ Float - The sine wave frequency
AMP Float 1.0 The sine wave amplitude
PHASE Float 0.0 The initial phase in radians
