Abstract: A cognitive signal converter adapted to produce a digital output signal based on an analog input signal comprises an analog-to-digital converter (ADC) and a cognitive network. The ADC is adapted to produce a digital converted signal based on the analog input signal, a sample clock signal and a process clock signal by sampling the analog input signal in accordance with the sample clock signal and quantizing each analog input signal sample based on the process clock signal. The cognitive network is adapted to receive the digital converted signal of the ADC, control at least one of the sample clock signal and the process clock signal based on the received digital converted signal and one or more characteristics of the analog signal source, and produce the digital output signal based on the received digital converted signal. Corresponding integrated circuit, electronic device and method are also disclosed.

Abstract: A cognitive signal converter connectable to an analog signal source via an analog signal input port and adapted to produce a digital output signal based on an analog input signal received via the analog signal input port is disclosed. The cognitive signal converter comprises an analog-to-digital converter and a cognitive network. The analog-to-digital converter is adapted to produce a digital converted signal based on the analog input signal, a sample clock signal and a process clock signal by sampling the analog input signal in accordance with the sample clock signal and quantizing each analog input signal sample, wherein the quantizing process is operated by the process clock signal.
