The real (noisy) oscillation signal (Fig. 36) where A(t) is an amplitude-modulating (AM) component and )(t) is a phasemodulating (PM) component [52]. The spectral component of the oscillation signal and the corresponding AM and PM noise components at certain offset frequency 'f from the carrier are depicted by Fig. 6. 6: AM and PM modulated components of an oscillation signal. As the AM component can be removed by, for example, an amplitude control mechanism of an oscillator [53,54], the PM component determines a deviation from the ideal case (Eq.

Spectrum-Signal Transformation 43 However, frequency- and phase-modulated signals (most often employed modulation techniques in mobile communication systems [57]) don’t carry the same information in the lower and the upper parts of the spectra [6,8,58]. Therefore, a certain degree of image rejection is necessary for the correct signal detection in homodyne receivers [6,8], where we can consider that the LB of the information spectrum (Fig. 4) is an image of the UB of the spectrum. 1 Image-Reject Zero-IF Architectures In order to avoid the successive and extensive filtering found in heterodyne receivers, without compromising the selectivity and sensitivity of the receiver, other techniques of coping with the image problem have been devised.

6, respectively. By processing the desired signal and the image signal in a different way, both architectures reject the image signal and transfer the desired signal. Namely, by mixing the incoming signal with two quadrature-phase oscillation signals (sine and cosine) and subsequently adding the downconverted signals in quadrature (900 shift in Fig. 5a), the desired signal adds constructively whereas the image signal is cancelled. 5: The Hartley architecture: a) a functional description, b) a practical implementation.
