Utilize analog and digital signal processing techniques in building a low-cost high-precision digital oscilloscope for high ...

Analog and digital signal processing techniques ... The smaller the α, the more attenuation to high frequency noises, with the cost of a smaller passband. Three different α values (0.5, 0.25, and ...

Furthermore, signal bandwidths may be dynamically reconfigured ... the frequency response of a channel varies with the frequency of an injected carrier. The passband ‘droop’ across FFT channel bin 0, ...

Also, due to the etched slots, the signal interference can be introduced by adding an additional microstrip line. Then, multiple transmission zeros (TZs) are therefore produced and enhance the ...

It is shown that the standard envelope-derived timing-recovery system may be significantly improved by zonal filtering of the received passband signal prior to forming the envelope. For ...
