    Abstract: An electronic apparatus for measuring a frequency of an electromagnetic signal emitted from a coordinate indicating device contacting a sensor pad, and method are provided. The electronic apparatus includes a signal receiving unit that receives the electromagnetic signal, a band-pass filter unit including a pair of band-pass filters that generates a first filtered signal and a second filtered signal by respectively filtering the electromagnetic signal in a first frequency range and a second frequency range corresponding to a center frequency of the coordinate indicating device, and a controller that acquires a frequency value of the electromagnetic signal based on a ratio value between the first filtered signal and the second filtered signal.

    Abstract: A touch screen device, an input device, and a control method thereof are provided. The touch screen device includes a channel electrode configured to receive a signal from an input device, a driver circuit configured to apply a drive signal to the channel electrode, a receiver circuit configured to receive the signal from the channel electrode, and a processor configured to control the driver to transmit an input device identification information to the input device such that, when a signal transmitted from the input device is received through the receiver circuit, based on a frequency of the received signal or a pattern of the received signal, the processor determines if the received signal is associated with the input device identification information transmitted to the input device. Accordingly, a touch screen device capable of touch inputting with respect to a plurality of input devices can be provided.
