Abstract: An active stylus and a method of generating wireless signals thereof are described. After the active stylus sends a first beacon signal, it determines whether to generate a first or second button signal. When the first and second button signals are both generated, the active stylus generates a first button transmission signal according to a first frequency, generates a second button transmission signal according to a second frequency, and sends out the first and second button transmission signals. Since the frequencies of the first and second button transmission signals are different, the simultaneously sent first and second button transmission signals can be separated by filtering or Fourier transform when a receiving end receives the first and second button send transmission signals. In this way, the overall time for transmitting the first and second button transmission signals can be shortened, thereby quickly transmitting the wireless signals.
