Abstract
Disclosed are a load resistor control based signal amplification apparatus and an audio terminal including the same. The signal amplification apparatus according to the exemplary embodiment of the present disclosure selects at least one load resistor based on a load value of an output terminal connected to an output end and controls a current by means of at least one selected load resistor to amplify the audio input signal and output the audio output signal.
Claims12
A signal amplification apparatus which amplifies an audio input signal,
- wherein at least one load resistor is selected based on a load value of an output terminal connected to an output end and a current is controlled by means of at least one selected load resistor to amplify the audio input signal and output the audio output signal.
A terminal which reproduces an audio, comprising:
- an audio input module which receives a digital signal based audio signal;
- a signal conversion module which converts the audio signal into an analog signal based audio input signal;
- an amplification processing module which selects at least one load resistor based on a load value of an output terminal connected to an audio output module and controls a current by means of at least one selected load resistor to amplify the audio input signal;
- and
- an audio output module which transmits an audio output signal amplified by a current controlled based on at least one selected load resistor to the connected output terminal.
