Fourier transform to strike a signal to the power spectrum --- welch method
Power spectrum estimated more than window ---- Law (multitaper method, MTM)
---- Power spectrum estimate of maximum entropy (maxmum entmpy method, MEM)
---- More than the estimated power spectrum signal classification (multiple signal classification, MUSIc)
The purpose of this document is to present how to use the Timer for the generation of a PWM signal tunable in frequency and duty cycle. As an application example, this document is based on a basic “MUSIc” synthesizer through an external buzzer. Example code is also available in the it.
