Receiver equalizer circuit, transmitter equalizer circuit, and electronic device

A receiver equalizer circuit, comprising:

• a signal input, a first signal processing channel, a second signal processing channel, and a filter circuit, wherein the first signal processing channel and the second signal processing channel are connected to the signal input, respectively,
• the first signal processing channel comprising a first analog-to-digital converter and a first digital down-converter provided downstream of the first analog-to-digital converter, wherein the first analog-to-digital converter is configured to digitize a signal processed by the first signal-processing channel, thereby obtaining a first digitized signal, and wherein the first digital down-converter is configured to down-convert the first digitized signal or a processed version of the first digitized signal, thereby obtaining a first down-converted signal,
• the second signal processing channel comprising a second analog-to-digital converter and a second digital down-converter provided downstream of the second analog-to-digital converter, wherein the second analog-to-digital converter is configured to digitize a signal processed by the second signal-processing channel, thereby obtaining a second digitized signal, and wherein the second digital down-converter is configured to down-convert the second digitized signal or a processed version of the second digitized signal, thereby obtaining a second down-converted signal, and
• wherein the filter circuit is connected to the signal processing channels downstream of the digital down-converters.
