UNIT TEST
1. Pseudo-random binary sequences are used for testing data transmission systems because
a. They resemble random data.
2. In random data, 1s and 0s
c. occur in definite patterns.
3. With pseudo-random binary sequences,
a. short runs occur more frequently than long runs.
4. The delayed output on the Pseudo-Random Binary Sequence Generator is used
c. to provide a sequence of a different length than that at the main output.
5. For white noise, the noise power is
a. independent of the bandwidth,
6. Gaussian white noise
c. is not band-limited.
7. Transmission errors occur in a data communications system
c. when the noise adds to or subtracts from the signal in such a way that the bit detected is different from the one transmitted.
8. The probability if error per bit
b. indicates exactly the number of errors per second.
