5 Questions
What is the main purpose of modulation in communication systems?
To upshift the frequency of transmission for practical transmission through free space
What is the relationship between the Nyquist sampling rate and the bandwidth of the analog signal?
The Nyquist sampling rate is twice the bandwidth of the analog signal
What is the purpose of quantization in the analog-to-digital conversion process?
To map the continuous amplitude values of the analog signal to a finite set of discrete values
What does the bit rate of an A/D process depend on?
Number of bits and sample frequency
How can quantization error in an A/D process be improved?
By increasing the number of quantization levels (increasing resolution)
