This paper presents the analogue of the time or frequency scaling theorem of continuous time/frequency Fourier Transform (FT) to the realm of Discrete Fourier Transform (DFT). The scaling property applies to scaling by integers which are relatively prime to the length of the DFT. The time reversal property of DFT is identified as a special case of this(More)
In 2007 we reported a flexible integrated circuit transceiver operating from 100 MHz to 2.5 GHz with continuous coverage over that range [1-2]. A new version of the chip is now available with improved performance and significant new features. Notable performance improvements include operation up to 4 GHz using the on-chip direct digital synthesizers (DDS)(More)
