Question 1: [5 points) Circle the correct choice for each of the following questions: 1 The Signal-to-Noise ratio of an ideal noiseless channel is (a) 0 (b) I (c) infinity (d)-1 2. In the mode of communications, only one of the two stations on the link can transmit, and the other station can only receive. (a) simplex (b) full duplex (c) half-duplex (d) none of 3. A stop bit in asynchronous serial communications is always (a)0 (b) 1 (c) none of the 4. Signal propagation time through a channel depends upon (a) the signal power (b) the noise 5. A color pixel is represented by the intensities of primary colors. (a) two (b) three (c) four the above. above power (c) the signal speed in the channel and the distance covered (d) none of the above. (d) five (e) seven (f) none of the above.
