Abstract:
Disclosed are a device and a method to convert emotional information. The device to convert emotional information comprises: a visual information extraction unit to extract visual information from an input image; an emotional information conversion unit to analyze the extracted visual information and convert the analyzed visual information into emotional information; and a sensory effect information generation unit to generate sensory effect information, which can be transmitted to a user, by determining the converted emotional information.
Abstract:
An embodiment provides a digital RF receiver including a signal converting unit which converts an RF signal received from an external device into a digital signal; a plurality of functional modules which processes the digital signal in accordance with a predetermined algorithm when the digital signal is inputted; and a signal processing controller which selects at least one of the plurality of functional modules to control the digital signal to be processed in consideration of whether an IF signal component is included in the digital signal or a sampling rate related with sampling information of the digital signal. [Reference numerals] (110) Low noise amplifier; (120) Signal converting unit; (130) Mixer unit; (140) Integer number decimation filter unit; (150) Rational number decimation filter unit; (160) DC offset compensator; (170) IQ mismatch compensator; (180) Channel selection filter unit; (190) Signal processing controller
Abstract:
PURPOSE: A digital front end receiver using a DC offset compensation technique is provided to perform the digital modulation of an RF receiver by implementing a digital front end with digital logic. CONSTITUTION: A DC offset compensation unit (120) removes DC offset elements from a signal inputted from a digital mixer to output the same. A cascaded integrator-comb (CIC) decimation filter (130) reduces a sampling rate of a signal inputted from the DC offset compensation unit to output the same. The DC offset compensation unit calculates the receiving signal average of the number of samples. The DC offset compensation unit estimates the DC offset elements included in a receiving signal.
