The user can get higher signal amplitude with a differential circuit thanwith a single-ended circuit. With the same power supply voltage, adifferential signal can provide double the amplitude as compared to asingle-ended signal. It also provides better linearity and SNR performance Differential circuits are fairly … See more The IF filter in a communications receive chain is basically a low-passfilter or band-pass filter. It is used for rejecting the aliasing signals alongwith the spurs generated by active components. The spurs include … See more In communication systems, when the IF frequency is quite high, some lowfrequency spurs need to be filtered out, such as the half IF spur. To do this,design a band-pass filter. For a band-pass filter, it is not necessary to … See more Because the receiver IF filter is used to reject spurs and aliasing signals,its stop band roll-off should be as fast as possible. However, faster roll-offmeans higher order components, and there are a few reasons high orderfiltering is … See more
