A digital radio communication system receives a signal with signal power S of 3 µW, and noise level of 200 nW, on a radio channel with upper cut-off frequency of 2.42 GHz, and a lower cut-of frequency of 2.40GHz. What is the maximum information bit rate (net bit rate exclusive of forward error correction codes) that can be supported by this line, in theory, according to ShannonHartley?

In what ways might the study of telecommunications inform the study of data transmission? Do they both come as a set or does one not? Explanations for your responses are appreciated.

3. Consider the two scenarios below: a. An electrocardiogram waveform is sampled by a computer connected to a medical imaging system. The scanner performs some discrete-time filtering and digital signal processing to determine the relative timing of the QRS complexes, in order to synchronize imaging with specific phases of cardiac contraction. The signal processing must preserve the relative timing between signal peaks before vs. after filtering. b. A medical training facility houses a simulated patient mannequin, which has several embedded pressure sensors that are sampled and filtered by a small microcontroller with limited memory and processing speed. The signals must be processed and displayed as quickly as possible, ideally in real time. In each scenario, what kind of discrete-time filter would be more advantageous, FIR or IIR? Explain your reasoning.

For a single-layer perceptron, which statement is true for a viable error function? Here w.x denotes the weighted sum of inputs. E=1 for any input for which the output is 1 and the classification is incorrect. E=-w.x for any input for which the output is 1 and the classification is correct. E=-1 for any input for which the output is 1 and the classification is correct. E=w.x for any input for which the output is 1 and the classification is incorrect.

7.26. The sampling theorem, as we have derived it, states that a signal x(t) must be sam- pled at a rate greater than its bandwidth (or equivalently, a rate greater than twice its highest frequency). This implies that if x(t) has a spectrum as indicated in Figure P7.26(a) then x(t) must be sampled at a rate greater than 2w2. However, since the signal has most of its energy concentrated in a narrow band, it would seem reason- able to expect that a sampling rate lower than twice the highest frequency could be used. A signal whose energy is concentrated in a frequency band is often referred to as a bandpass signal. There are a variety of techniques for sampling such signals, generally referred to as bandpass-sampling techniques. x(t) X(jw) 1 -02-01 (a) +00 p(t) 8(t-nT) Xp (t) W1 W2 W H(jw) x(t) p(t) H(jw) 1 T дід.

Compute the capacity and input distribution attaining it for the discrete memoryless channel X → Y with X = y = {0, 1, 2, 3} given by Y = X + Z mod 4, where Z takes on values from Z = {0, 1, 2, 3} with z(0) = 1/2, z(1) = 0, and z(2) = z(3) = 1/4.

Suppose that you noticed that flying two 60 mile trips was too much for a pigeon and you had to let the pigeon rest for 2 hours before returning. How does the “Winston Channel” compare to DSL under this circumstance?
