For each of the following scenarios, decide what type of DSP filter (lowpass, highpass, bandpass, or bandstop) you should use to solve the problem and give the cutoff frequency or frequencies of the filter. An AM radio receiver uses a continuous-time modulator tuned to 800 kHz to mix a radio signal down to complex baseband, where it is sampled by an ideal (aliasing-free) continuous-to-discrete- time converter at a sample rate of 30 kHz. The user wishes to listen to the station at 800 kHz (0 kHz in complex baseband). AM radio stations have carrier frequencies 10 kHz apart. (b) A recording was made with sample rate 400 Hz. There is a strong 60 Hz hum due to electrical equipment in the room that must be removed, but the rest of the recording should be preserved as well as possible. Allow for a transition band of 7/10 in your filter.
