WebOct 29, 2024 · RC polyphase filter is a complex analog filter and has asymmetric frequency characteristics with respect to DC. It is composed of resistors and capacitors, and has complex analog input/output ports. Since this type of filter can partially realize Hilbert transform, it can be used for generating orthogonal signals. In the field of wireless … WebSuch a filter is called a “polyphase filter.” But then, (1) The image is no longer in the adjacent channel and hence quite large; (2) Baseband ADCs must digitize a broad bandwidth, consuming high power; (3) Polyphase filters are generally quite power hungry. Implementations using polyphase filters are not very common today.
