Problem Five Consider a serial port operating with a baud rate of 10,000 bits per second. Draw the waveform occurring at the UOTX output (voltage levels are +3.3 and 0) when the ASCII 'a' (0x61) is transmitted on UARTO. The protocol is I start, 8 data and 1 stop bit. UARTO is initially idle, and the software writes the Ox61 to UARTO DR R at time=0. Show the UOTx line before and after the frame, assuming the channel is idle before and after the frame.

Consider a circuit designed as follows: • one 1-bit register (like those discussed in class), with an attached clock • one not gate • wire A connects the register's ouput and the not's input • wire B connects the not's output and the register's input If we put a 1 onto wire B: A. wire A gets a 0 immediately B. wire A gets a 0 after the short delay it takes the gates in the register to finish work C. wire A gets a 0 after the next clock tick D. wire A gets a 1 immediately E. wire A gets a 1 after the short delay it takes the gates in the register to finish work O F. wire A gets a 1 after the next clock tick
Consider the problem of servo control using PWM signals. Assume we have the following requirements or given conditions. • The repetition period of the PWM pulse for servo control is 20 ms. • The pulse width is between 1.0 to 2.0 ms, with 1.5 ms setting the servos to the center. • We need a resolution of no less than 1 us (micro second) for the pulse width change. • The timer used for the PWM generation has a 16-bit prescaler and a 16- bit counter. • The clock to the prescaler is 10 MHz. Determine the following (which may not be unique): 1. The range of PSC that satisfies the requirements for resolution and period of the pulses.
Draw a circuit to implement a switching network with two data inputs (A and B), two data outputs (C and D), and a control input (S). If S=1, the network is in pass-through mode: C=A and D=B. If S=0, the network is in crossing mode: C=B, and D=A. Use the most reasonable combinational building blocks or gates. Label the inputs and outputs.
2. Consider a unit-energy root-raised-cosine (RRC) pulse which spans over 8 symbol durations. We take 10 samples per symbol (sps) from this RRC pulse. Write an RRC filter function that employs pulse-shaping using the RRC pulse described above. (If there is a single symbol and s=[1 0], the energy of the corresponding length-81 samples vector should be equal to 1.) The parameters of the RRC pulse are roll-off factor, span, and samples per symbol. You should write your pulse-shaping function according to the prototype given below txFilt = myRRCFilter(s, rf, span, sps) where txFilt is the pulse-shaped signal (transmitted signal), s denotes the transmitted symbols, rf is the roll-off factor, span is the span of the filter, and sps is the samples per symbol.
Design a Moore FSM for a Sequence Derector that detects five consecutive bits of "zero" in the input stream of bits, labeled x. The output z equals 1 if, during five consecutive clock cycles, the input x was equal to "zero". Once the sequence is detected, the FSM returns to the initial state S0. Add an asynchronous reset, active low, to the FSM.
A car manufacturer proposed to implement a simple DCS along a 50 m-long engine production line. The proposed system consists of a 16-bit PLC system, three sensors, and four mechanical actuators. The system components are interconnected using a copper wire network solution. The transmission speed of the network is 40 kbits/s. Two types of network configuration are to be considered, a CAN-based network, and a centralized controller network. A) Draw simple diagrams to show the difference between these two network configurations. B) In CAN, explain why logic '1' is referred to as Recessive logic, and logic '0' is referred to as Dominant logic.
