== Generation == A chirp signal can be generated with [[analog circuit]]ry via a [[voltage-controlled oscillator]] (VCO), and a linearly or exponentially ramping control [[voltage]].{{fact|date=February 2025}} It can also be generated [[Digital data|digitally]] by a [[digital signal processor]] (DSP) and [[digital-to-analog converter]] (DAC), using a [[direct digital synthesizer]] (DDS) and by varying the step in the numerically controlled oscillator.<ref>{{cite book |doi=10.1109/ICTC.2014.6983343 |chapter=Implementation of DDS chirp signal generator on FPGA |title=2014 International Conference on Information and Communication Technology Convergence (ICTC) |date=2014 |last1=Yang |first1=Heein |last2=Ryu |first2=Sang-Burm |last3=Lee |first3=Hyun-Chul |last4=Lee |first4=Sang-Gyu |last5=Yong |first5=Sang-Soon |last6=Kim |first6=Jae-Hyun |pages=956β959 |isbn=978-1-4799-6786-5 }}</ref> It can also be generated by a [[YIG oscillator]].{{clarify|date=April 2015}} {{clear}}
