FIELD: radio engineering, communication.
SUBSTANCE: encoding device can reduce input signal sampling, perform basic encoding of the input signal with reduced sampling, perform frequency conversion of the input signal and perform encoding with bandwidth extension using the basic signal of the input signal in the frequency domain.
EFFECT: high accuracy of encoding and decoding a signal in high-frequency band extension modes.
