Abstract
A transmission and reception apparatus, system for transmitting and receiving signals, and method for transmitting and receiving signals are disclosed. In one example, a transmitting part produces an output signal including a first digitally modulated signal. A receiving part includes a mixer circuit and receives an input signal including a second digitally modulated signal. A folding signal may be present as a function of the first digitally modulated signal and a clock signal used to produce the first digitally modulated signal. The mixer circuit performs frequency down conversion on the input signal, and may also be configured to perform a harmonic wave removal function on the input signal that reduces the presence of the folding signal from the input signal. The receiving part may further include a filter circuit that receives the frequency-down-converted input signal from the mixer circuit and selects a predetermined reception signal from the frequency-down-converted input signal.
