The operation of a synchronous receiver is somewhat similar to the UART receiver discussed in Section 11.3, except both data (RxD) and a data clock (Dclk) are transmitted so there is no need to synchronize data with a local clock, and no start and stop bits are required. As shown below, when 8 bits of data are transmitted, the clock is actually active for nine clock times and then it becomes inactive. On the first eight clocks data is shifted into the receive shift register (RSR), and on the ninth clock, the data is transferred to the receive data register (RDR) and the RDRF flag is set.
(a) Draw a block diagram for the synchronous receiver, including a counter. (Note: A state machine is not necessary, but generation of control signals Load and Shift is required.)
(b) Write synthesizable VHDL code that corresponds to (a). Signals Load and Shift should appear explicitly in your code.
Treat the plasma diameter as equal to the spot size generated by the laser - The actual diameter of the plasma is related to the incident field power and approaches the spot diameter as the power of the incident field is increase several times over..
In designing a low-pass filter for an audio system, the filter stop band attenuation must be at least 40 dB at a frequency that is 2 times the passband frequency. The attenuation in the passband must be less than 1 dB.
Maximum value of frequency deviation is fixed at 75 kHz for commercial broadcasting by radio. Modulation frequency W = 15 kHz, then find the transmission bandwidth of signal and deviation ratio.
Loop antennas are very common and are often used by amateur radio sites. In fact, the figure on the right is provided as an example what one may find when searching for loop antennas on the web.
a lightning bolt carrying 20000 A lasts for 20 microseconds. if the lightning strikes a tractor, determine the charge on the tractor if the tires are assumed to be perfect insulators.
A voltage of 60cos(4πt) V appears across the terminals of a 3mF capacitor. Calculate the current through the capacitor and the energy stored in it from t=0 to t=0.125 seconds.
Sketch the pulse shape. - Write the integral expression for the Fourier transform of x(t). - Can you infer that you only need to integrate the product of two cosines?
Now, we want to build a circuit that counts the number of 1s in a 6-bit unsigned numbers using full and half adder circuits as building blocks. Design the simplest circuit that can accomplish this task.
Prove that the potential cannot have a minimum in an uncharged region of space. Prove therefore that a point charge cannot be in stable equilibrium under the action of electrostatic forces in an uncharged region.
The two-wire 120-V supply line from the electric power company to the consumer has a resistance of 0.03 ohm. If a short circuit occurs at the consumer's residence, find the current that flows through the short-circuit.
What happens if R was infinite in parallel RLC circuit and What happens if R was zero in parallel RLC circuit what will be the circuits can we still apply the neper frequency now which will be zero
A press delivers a force of 8000 N throughout a distance of 18 mm each stroke. Select a number of strokes per minute and determine the rate of work output per second. If the press efficiency is 90%, what average torque must be provided by a 1750-..
