Abstract(in English) | In conventional direct digital synthesizers (DDSs), tuning frequency steps are uniquely determined by clock frequencies and bit width of phase accumulators. We designed a new DDS with an extended phase accumnlator whose operation cycle can be controlled. This DDS can provide lowspurious signals whose frequencies are given by arbitrary fractional expressions. Experimental results demonstrate successful frequency synthesizer operation in which the tuning frequency step is selected flexibly. |
