Answer:

Show the resulting when the input signal is modulated onto a 2000 Hz sine wave using amplitude modulation:
What sampling rate do you need to use to reconstruct the voice input reliably ? (10 pts)

Each sample is represented by an integer value between 64 and 63.
What is the data rate of a voice transmission using the above scheme: (10 pts)

The receiver reads the transmission at precisely the middle of its clock to determine the value of the transmitted bit.
The sender's clock runs at 1000 Hz and the receiver's clock runs at 999 Hz.
Suppose the receiver does not resynchronize its clock to the sender's clock.
If the sender's and the receiver's clocks are synchronized at the start of a (long) transmission, which bit poistion is the first bit that the receiver will receive incorrectly due to the clock drift ?


Answer:

Answer:

Answer:
Use 4 units in the graph below to transmit each bit
Use 2 sine waves for each bit
Answer: (3 ots)
Use 4 units in the graph below to transmit each bit
Use 2 sine waves to transmit a 0 bit and 4 sine waves to transmit a 1 bit
Answer: (3 pts)
