1. A transmitter for transmitting an electrical signal to a touch sensitive device according to a transmitter status, so that after analyzing the electrical signal, the touch sensitive device is able to find out the transmitter status and a relative position of the transmitter with respect to the touch sensitive device, the transmitter comprising a processing module and a sensor module including at least a pressure sensor, wherein the pressure sensor is used for sensing a contact pressure level between the transmitter and the touch sensitive device, when the pressure sensor senses a contact pressure, it corresponds to a first electrical signal, when the pressure sensor does not sense any contact pressure, it corresponds to a second electrical signal, the first electrical signal includes a signal of a first frequency and does not include a signal of a second frequency, and the second electrical signal includes the signal of the second frequency and does not include the signal of the first frequency, wherein the electrical signal is mixed from a plurality of signals having different frequencies concurrently, wherein the signal strength of the electrical signal corresponds to a status of a first sensor having x possible statuses in the sensor module, wherein a ratio of the signal strengths of a first frequency to a third frequency mixed in the electrical signal corresponds to a status of a second sensor having y possible statuses in the sensor module. |
