Abstract
A method for extended-pulse sampling includes providing a continuous-time signal comprising a frequency spectrum within a predetermined passband. The continuous time signal is sampled with a plurality of discrete sample pulses having a pulse shape in a time domain that is an impulse response of a filter having the predetermined passband. The plurality of discrete time samples of the continuous-time signal is then provided to an output.
Claims41
A method of extended-pulse sampling, the method comprising:
- a) providing a continuous-time signal comprising a frequency spectrum within a predetermined passband;
- b) sampling the continuous time signal with a plurality of discrete sample pulses having a pulse shape in a time domain that is an impulse response of a filter having the predetermined passband;
- and
- c) providing the plurality of discrete time samples of the continuous-time signal to an output.
An extended-pulse sampling system comprising a sampler having an input configured to receive a continuous-time signal comprising a frequency spectrum within a predetermined passband, the sampler sampling the continuous time signal with a plurality of discrete sample pulses having a pulse shape in a time domain that is an impulse response of a filter having the predetermined passband, thereby generating a plurality of discrete time samples of the continuous-time signal at an output.
An extended-pulse sampling system comprising:
- a) an input configured to receive a continuous-time signal comprising a frequency spectrum within a predetermined passband;
- b) a splitter having an input electrically coupled to the input and configured to provide a first portion of the received continuous-time signal to a first output and to provide a second portion of the received continuous-time signal to a second output;
- c) a first sampler electrically coupled to the first output of the splitter that samples the first portion of the continuous time signal at a first time with a plurality of discrete sample pulses with a pulse shape in a time domain that is an impulse response of a filter having the predetermined passband and that provides the sampled first portion of the continuous time signal to an output;
- d) a second sampler electrically coupled to the second output of the splitter that samples the continuous time signal with at a second time with a plurality of discrete sample pulses having the pulse shape in the time domain that is the impulse response of the filter having the predetermined passband and that provides the sampled second portion of the continuous time signal at to output;
- and
- e) a switch having an input configured to connect to the output of the first sampler at the first time and to connect to the output of the second sampler at the second time, thereby providing a discrete time sample of the continuous-time sample at an output.
