Abstract: In a receiver of a transmission system in which the data transmission rate is not an integer multiple of the spacing between transmission channels, a single oscillator is used to generate both the system clock used to process the data signal as well as the mixing signal used to downconvert the received RF signal to an intermediate frequency (IF). The frequency error in the IF signal that results from mixing the RF signal at a less-than-ideal mixing frequency is compensated by selecting an appropriate mixing signal frequency applied when downconverting the IF signal to baseband. In a transmitter, the mixing signal frequency used to upconvert the outgoing baseband signal to IF is selected to pre-compensate for the frequency error resulting from upconverting the IF signal to RF using a less-than-ideal mixing frequency. In either case, the receiver/transmitter can be implemented without having to provide a dedicated reference oscillator for converting signals between RF and IF.

Abstract: The present invention provides stain-inhibiting protection to glass surfaces of stacked glass sheets utilizing one or more water-soluble organic acid dispersed in a matrix of a water-soluble polymer or mixtures thereof. Suitable water-soluble organic acids may be found in the groups consisting of hydroxy mono, di, tri and tetra carboxylic acids. In the preferred form of the invention, components such as humectants, bactericidal and bacteriostatic agents and surface active (wetting) agents may be included in the composition.
