摘要： A signal processing device for a keyboard and a signal processing method thereof. The signal processing device for a keyboard includes a key scanning unit, a pointer rod scanning unit, an analog-to-digital conversion unit and a processing unit. The key scanning unit is connected with the keys for generating a first digital input signal. The pointer rod scanning unit is connected with the pointer rod for generating an analog input signal. The analog-to-digital conversion unit is connected with the pointer rod scanning unit and receives the analog input signal, and converts the analog input signal into a corresponding second digital input signal. The processing unit is connected with the key scanning unit and the analog-to-digital conversion unit for receiving the first digital input signal and the second digital input signal, and processes the first digital input signal and the second digital input signal by time sharing.
