1.	Quadrature sampling uses ____ to ____ the bandwidth available for a particular sampling rate.(a) integration, quadruple(b) complex numbers, quadruple(c) complex numbers, double(d) integration, doubleI had been asked this question by my school teacher while I was bunking the class.My enquiry is from ADC Tradeoffs topic in section Technology Tradeoffs in Software Defined Radio of Cognitive Radio
Answer» Right option is (C) complex numbers, double To EXPLAIN: Quadrature sampling uses complex numbers to double the bandwidth AVAILABLE for a particular sampling rate. It is a polyphase filter. Real signals are combined with cosine and sine reference SIGNAL generated by a local oscillator.
