A bandpass signal, on the other hand, has non-negligible frequency content only in a finite band of frequencies centered about a certain frequency much greater than zero. An example of a bandpass signal is a radio signal transmitted over the air, such as off-the-air radio and TV signals....
*bandpass *stopband Anagrams * baseband English Noun (en noun) (telecommunications) The frequency range occupied by a message signal prior to modulation. (telecommunications, noun adjunct) A method of transmission in which only one frequency channel is used at a time. ...
Baseband Baseband http://en.wikipedia.org/wiki/Baseband The figure shows what happens with AM modulation:
() for converting the baseband signal () supplied by the digital mixer () into an analog bandpass signal (), and an analog mixer (), which transforms the analog bandpass signal () with a predetermined constant factor (f) into a real bandpass signal () which is centered around the ...

Digital modulation is the process by which a digital baseband signal that contains the source of information is imparted with a bandpass signal of carrier frequency fc. The bandpass signal is said to be modulated, while the baseband signal is called the modulating signal. Therefore, the power ...
It is in accord with software radio, bandpass sampling and coherent demodulation techniques are used in the demodulation, and also make analysis with the spectrum. 根据软件无线电的思想,用可编程器件FPGA实现了QPSK解调,采用带通采样技术对中频为70MHz的调制信号采样,通过对采样后的频谱进行分析,用相干解调...
