1.	Digital translation of a baseband signal into an IF is an example for ____(a) continuous-time point operation(b) continuous-frequency point operation(c) discrete-time point operation(d) discrete-frequency point operationThis question was posed to me during an interview.I would like to ask this question from Essential Function of Software Radio topic in division Software Defined Radio Architecture of Cognitive Radio
Answer» The CORRECT option is (c) discrete-time point operation Explanation: Digital translation of a BASEBAND signal into an IF is an example for Discrete-time point operation. Discrete-time point operation involves the multiplication of discrete time-domain baseband WAVEFORM by a discrete reference CARRIER to GIVE sampled in-phase IF waveform.
