Downconvert frequency
WebMay 1, 2024 · Baseband is some low frequency that is convenient. The bandwidth stays the same, only the center frequency is changed. If we wanted, we could mix the above signal with an $800$ MHz carrier and take the difference frequency to get a signal that ranged between $75$ and $125$ MHz for our baseband signal. WebMar 10, 2024 · A complex NCO frequency translating a complex input is shown in the block diagram in this post: Recovering signal for psk. ... then you would need a -800 KHz to downconvert it, and a real NCO at 200KHz has components at +/- 200 KHz (as an analog signal) and when sampled at 1000 KHz also has a component at -800 KHz).
