A novel and useful fast hopping frequency synthesizer and transmitter associated therewith. The frequency synthesizer and transmitter incorporates a digitally controlled oscillator (DCO) adapted to operate open loop. Instantaneous frequency switching is achieved by changing an oscillator tuning word (OTW) to imitate the three oscillators of a UWB transmitter. In one embodiment, the DCO can change the frequency instantaneously within the 1/f_T of the varactor devices used to construct the DCO. An all digital phase lock loop (ADPLL) is used for offline calibration prior to the start of packet transmission or reception. Any phase shift during the switching is tracked by a digital circuit in the transmitter. In a second embodiment, additional frequency accuracy is provided by use of a numerically controlled oscillator (NCO) that functions to generate a fine resolution complex exponential waveform which effectively shifts the synthesized frequency. A mixer applies the waveform to the I and Q data samples prior to conversion to the digital domain.

A method for obtaining a concentrated alcohol solution from a lignocellulosic feedstock. The lignocellulosic feedstock is hydrolyzed to prepare a sugar solution. The sugar solution is fermented to produce a fermentation broth comprising alcohol and at least about 1 g ammonium ions/kg fermentation broth. The alcohol in the fermentation broth is then concentrated by distillation to produce an alcohol-enriched vapour. Either before distillation, during distillation or during the azeotrope breaking process, the concentration of ammonia in the alcohol-enriched vapour can be reduced by acid addition to at most about 300 ppm. The alcohol in the alcohol-rich vapour is then further concentrated by an azeotrope breaking process to provide the concentrated alcohol solution.
