Do your simulation with IQ baseband, and then pretend "0" is any other carrier frequency you want. That is what the power spectrum will look like. The actual carrier frequency doesn't have any effect. | |

| Oct 26, 2022 at 14:16 | comment | added | Marcus Müller | well, basics question time! What is the maximum frequency you can represent with a sample rate of 250 MHz? | |
| Oct 26, 2022 at 13:18 | comment | added | QAM | I have baseband signal with sample rate of 250MHz and its bandwidth is 200MHz. Im trying to upconvert it to carrier frequency. Carrier frequency can be for example 1000MHz. @MarcusMüller | |

| Oct 26, 2022 at 11:01 | comment | added | Marcus Müller | It's not quite clear what you're doing. What's the sampling rate? If you say you have a signal, do you mean baseband or bandpass signal? | |
