A date link protocal uses the CRC16 polynomail for error detection
A) suppose the data block (including the 16 check bits) has n=1000 bits how many possible received black are there?
B)On a particular transmission a lot of errors occur in the receiver block. in fact the n bits of received block are just random 0's and 1's. what is the probabilty that is black will be valid code?
Important information about Examination of a digital radio link A. A digital radio link operates at a frequency of 75 MHz and uses ideal RRC filters with nroll off factor r = 0.2 in the transmitter
A sample of 16 pvc valves for gas engines is randomly selected from a very large batch, and tested. Let X denote the number of valves out of the 16 selected that are found to be defective when tested. Valves are defective or non-defective independ..
The bellows, diaphragm, and Bourdon tube pressure sensors all exhibit second order time response. This means that a sudden change in pressure will cause an oscillation in the displacement and, therefore in the sensor output.
Sizes are given as the diameter of the pizza in inches. The cost of a pizza is based on the size. Bob would like to know which size of pizza has the lowest cost per square inch. a. Identify the inputs and outputs for this problem.
Contemporary computers often have more than 100mb of physical memory. Suppose the page size is 2 KB. How many entries would an associative memory need in order to implement a page table for the memory
Design a circuit to capture the pressing of buttons (momentary switches). The circuit should have two LEDs "A" and "B", and two buttons, "A" and "B". Whichever button was last pressed should determine which of the two LEDs is lit.
Find Rin, Avo, and Ro. Also, if a load resistance of 10k ohm is connected to the output, what overall voltage gain Gv is realized. Now, if a 0.2 V peak sine wave signal is required at the output, what must the peak amplitude of Vsig be.
A temperature sensor has a static transfer function of 0.15 mV/C° and a time constant of 3.3 s. If a step change of 22° to 50° C is applied at t=0, find the output voltage at 0.5 s from t=0s to t=10s. What is the indicated temperature at these tim..
A system, linear and time invariant is described by the following difference equation: 4y[n-2] + 2y[n-1] + y[n] = x[n] a) Determine if the system is stable. b) Find the system response to the unit step.
The fermi energy level for a particular T = 300K is 6.25 eV. The electrons in this material follow the Fermi-Dirac distribution function. (a) Find the probability of an energy level at 6.50 eV being occupied by an electron.
A linear CW product detector local oscillator has a 500 Hz error while detecting an AM signal. What will the receiver's output sound like What if the receiver is listening to a DSB or SSB signal
With |V| = 100 V, the instantaneous power p(t) into a network N has a maximum value 1707 W and a minimum value of -293 W. Find a possible series RL circuit equivalent to N.
