Abstract
A transmitter for remote control, the transmitter includes a first analog-to-digital converter (ADC) configured to receive a first audio signal from a electronic device and convert the first audio signal to a first direct-current (DC) signal, a first boost circuit electrically connected to the first ADC to receive and amplify the first DC signal, and a transmission module electrically connected to the first boost circuit to receive the amplified first DC signal, wherein the amplified first DC signal is configured to modulate a carrier signal generated by the transmission module and the first audio signal is one of a left channel audio signal and a right channel audio signal output from the electronic device through an audio connector.
