The output levels of a 4-bit DAC produces the following set of voltage levels, starting from code 0 and progressing through to code 15:
0.0465, 0.3255, 0.7166, 1.0422, 1.5298, 1.8236, 2.1693, 2.5632.8727, 3.3443, 3.6416, 4.0480, 4.3929, 4.7059, 5.0968, 5.5050
What is the full-scale range of this DAC?
A 100Ω load needs 10mA to operate correctly. Design a practical power source to provide the needed current. The smallest source resistance you can practically design for is 50Ω, but you can add any other series resistance if you need to.
A four-stage shift register is to be used to generate two sequences of length 7 and 15. A sequence of length 7 is generated when a control signal c is set to 1; when c is set to 0, a sequence of length 15 is generated. Write the VHDL code for the ..
The coherent detector for the demodulation of DSB-SC fails to operate satisfactorily if the modulator experiences spectral overlap, explain the reason for this failure.
A certain busy student looks at X (ω), concludes that its bandwidth is really 10 Hz, and decides that the sampling rate 20 Hz is adequate for sampling x (t). Sketch the spectrum of the signal sampled at a rate of 20 Hz. Can she reconstruct x (t) f..

A hollow sphere with inner and outer radii of R1 and R2, respectively, is covered with a layer of insulation having an outer radius of R3. Derive an expression for the rate of heat transfer through the insulated sphere in terms of the radii, the t..
find the fourier series coefficients of z(t) (use the results of a) and b) along with the multiplication property of continuous time fourier series coefficients). find the fourier series coefficients of z(t) through direct expansion of z(t) in tri..
Given that Xi, Yi and Ci represent the addend bits and carry-in at position i, i.e. Stage i, specify and compare the logical expressions for Si and Ci+1, i.e. the sum and carry-out from Stage i, between the one-bit half adder, the one-bit full add..

You are required to determine that this next generation transmission system will require a spectral efficiency of 5 bits/sec per Hertz.
The output of the channel is again digitized, resulting in the following differential RMS output levels: 400 Hz: 0.01 mV RMS, 1160 Hz: 0.1 mV RMS, 3200 Hz: 0.13 mV RMS. Calculate the PSR and PSRR at each frequency
