Digitizing an Audio Signal, PAM, ADC, An audio signal has a bandwidth that extends from 100 Hz to 10 kHz. The signal is sampled to create a PAM signal and then digitized by an analog to digital converter (ADC) that has 8 bits.
Interface TTL logic to 120 VAC lamp. In this part of the lab, you will interface lowpower solid state electronics to the "outside world" by switching the 120 VAC lamp on and off using the AND gate from the previous experiment.
In class we saw an example of 'Beat note'. In this problem we consider a more general case. Let fc > 0, fd > 0 and define a signal x as.
Begin with a breadboard, wire, an RGB LED and some resistors. Using the forward voltages given in the RGB LED datasheet, calculate the correct current-limiting resistors needed to light each color of the LED (assuming VDD = +5V).
An assembly line can produce 90 units per hr. The line hrly cost is $4500 on stright line ( the first 8 hrs). Workers are guaranteed a minimum of 6 hrs. There is a 50% premiun for overtime (time and a half), how ever productivity drops by 5%.
The 24-bit data field of a packet is given by 0xBC603F. The packet contains a CRC with the generator polynomial given by X 3+X+1 a) Find the CRC checksum. Provide the complete code-word including the checksum in hex.
(a) Determine the cone angle that will match the line to an infinite length biconical antenna. (b) For the cone angle of part (a), determine the two smallest cone lengths that will resonate the antenna.
Solve Using Gauss-Seidel Method (Perform Four Iterations) Using the Gauss-Seidel method and the initial guess X1(0)=1, solve the following equation (x_1)^2 - 6x_1 + 2 = 0
Design the system which finds the most popular (one most often generated) symbol called winner in each block of 32 input symbols. The system reports the number of winners and their value. Use only 2 data inputs multiplexers and shift registers.
Consider a chip design using 10 mask levels. Suppose that each mask can be made with 98% yield. Determine the composite mask yield for the set of 10 masks.
Let us assume that a synchronouse 3 phase alternator produces a no-load line voltage of 13.2 KV. if a load having a lagging power factor of 0.8 is connected to the machine, must the excitation be increased or decreased
Draw a state diagram for an FSM (Moore machine) with no inputs and three outputs x, y, and z, where xyz should always exhibit the following sequence: 000, 001, 010, 100, repeat. Make 000 as the initial state.
