Distinguish baseband and bandpass
Baseband transmission uses a low-frequency representation of the information signal. Bandpass transmission shifts the representation around a carrier. Pulse shaping, the channel response and receiver filtering determine how adjacent symbols interfere.
Control intersymbol interference
The Nyquist zero-ISI criterion concerns the sampled overall pulse response. It is distinct from the sampling theorem for reconstructing a bandlimited waveform. Raised-cosine pulse shaping trades additional bandwidth for practical transition behavior. Equalization attempts to compensate for channel distortion; it cannot remove arbitrary noise without trade-offs.
Try it
For an ideal raised-cosine baseband pulse shape with symbol rate and roll-off , one-sided baseband bandwidth is . State the bandwidth convention before applying this result to an RF channel.
Check your understanding
Why can two pulses that overlap in time still have zero ISI at the sampling instants? Draw the relationship between a baseband spectrum and its bandpass translation.
Pause and recall
Without looking back, explain the main idea, recall a key definition or formula, and describe when it applies. Include assumptions and units where relevant. Revisit any step you could not explain.
