14.1 For each term, give a definition in 32 words or
less.
a) Master-slave
b) Multi-drop
14.2 For each pair of terms, compare and contrast in
32 words or less.
14.4 Consider a telephone line with a channel
bandwidth of 2 kHz and SNR of 40 dB. What is the
maximum data rate possible?
14.8 Consider how the ACK bit is used in a CAN
network.
2. 14.9 If the CAN channel is noisy, it is possible that
some bits will be transmitted in error. Assume there
are four nodes: one is transmitting, and three are
receiving. What happens if a data bit is flipped in the
channel due to noise being added into the channel?
14.10 Consider a situation where two microcontrollers
are connected with a CAN network. Computer 1
generates 8-bit data packets that must be sent to
Computer 2, and Computer 2 generates 8-bit data
packets that must be sent to Computer 1. The packets
are generated at random times, and the goal is to
minimize the latency between when a data packet is
generated on one computer to when it is received on
the other. Describe the CAN protocol you would use:
11-bit versus 29-bit ID, number of bytes of data, and
bandwidth. Clearly describe what is in the ID and how
the data is formatted.
14.13 Consider a situation where four
microcontrollers are connected together using a CAN
network. Assume for this question that each frame
contains 100 bits. Also assume the baud rate is 100,000
bits/sec; therefore, it takes 1 ms to send a frame.
Initially, the CAN controllers are initialized (i.e., all
computers have previously executed CAN_Open).
