Question 2 of 14 (1 point) | Question Attempt: 1 of 1 1 2 3 4 5 6 7 8 9 10 11 In the scientific method experiment, pillbugs were added to a choice chamber with two sides connected by a channel that allowed the pillbugs to either side. One side of the container was lined with sand (no nutrients) and the other side was lined with cornstarch which contained nutrients. Based on your understanding of the experiment and its variables, select the INCORRECT statement below. O A controlled experiment allows scientists to test hypotheses and to draw conclusions based on reproducible results. O A controlled experiment allows comparison between a control group and a test (experimental) group that has been exposed to an experimental factor (the variable). O A controlled experiment is often conducted in multiple trials. O Experiments are typically conducted with one type of variable such as an independent, dependent, or standardized variable.

Digital Communication 3 Question, please from a to e are to be solved, please? 12.3. Consider the DS/BPSK spread-spectrum transmitter of Figure 12.9a or b. Let x(t) be the sequence 1 0 0 1 1 0 0 0 1, arriving at a rate of 75 bits/s. where the leftmost bit is the earliest bit. Let g(t) be generated by the shift register of Figure 12.7. with an ini- tial state of 1 1 1 1 and a clock rate of 225 Hz. (a) Sketch the final transmitted sequence x(t)g(t). (b) What is the bandwidth of the transmitted (spread) signal? (c) What is the processing gain? (d) Suppose that the estimated delay, T, of Figure 12.9c is too large by one chip time. Sketch the despread chip sequence. (e) Choose a decision rule for deciding on x(t) and identify the errors
