ADC USE WITH MULTIPLE SIGNAL MODES

摘要

A signal is received and whether a signal mode of the signal is a first signal mode or a second signal mode is determined. A gain of a variable gain amplifier is adjusted to a first gain value if the signal mode of the signal is determined to be the first signal mode or a second gain value if the signal mode of the signal is determined to be the second signal mode. The signal is amplified with the variable gain amplifier by the first gain value or the second gain value. The signal is converted to a digital signal with an analog to digital converter after the signal is amplified with the variable gain amplifier by the first gain value or the second gain value.
