Question: Suppose the PLL of Fig. is locked. Now, we replace R1 with an open circuit. What happens at the output as time passes? Consider two cases: a noiseless VCO and a noisy VCO. This example shows that if the VCO (excess) phase does not drift with time, the feedback loop can be broken.
If the we decrease the capacitor value to 2.2 μF, what is the RMS noise voltage at the RC fi lter output?
Derive and plot Hugo's Engel curve for donuts. How much does his weekly budget have to rise for Hugo to buy one more donut per week?
Using 4 PSK or 2 PSK with the same total power as a reference, calculate the Eb/No versus Pe waterfall plot and compare the asymptotic coding gain of the coder/encoder.
Suppose a uniform magnetic field exists ina finite regionof space. Can a charged particle be injected into this region from the outside and remain trapped in the region by magnetic force alone
A square plate of titanium is 12cm along the top, 12cm on the right side, and 5mm thick. A normal tensile force of 15kN is applied to the top side of the plate. A normal tensile force of 20kN is applied to the right side of the plate.
consider the following two first-order transfer functions H1 (z) = z + b/z + a , a = 0.3, b = - 0.4 H2(z) = bz + 1/z + a , a = 0.3, b = - 0.4 (a) draw the pole-zero plot for both transfer function H1(z) and H2(z)
Write down an expression for the pdf of Z.
A 400/100 V, 10 kVA, 2-winding transformer is to be employed as an autotransformer to supply a 400 V circuit from a 500 V source. When tested as a 2-winding transformer at rated load, 0.85 pf lagging, its efficiency is 0.97%.
For the grounded gate p-pullup pseudo NMOS circuit shown below assume the load capacitor, CL, is initially discharged, and that the input voltage abruptly drops from Vdd to zero. Derive the equation for the output voltage charging behavior.
State the relationship between D and E in a dielectric material. How does it simplify the solution of field problems involving dielectrics?
Many ink-jet printers have six cartridges for different colored ink: black, cyan, magenta, yellow, light cyan and light magenta. A multibit signal in such a printer indicates selection of one of the colors. Devise a minimal length code for the sig..
