Gaussian white noise, perfectly band-limited to 0-10MHz, is passed through a perfectly rectangular filter of bandwidth 18 kHz, gain 3 dB, and center frequency 455 kHz. If the RMS voltage of the input noise is 1 volt, what is the RMS voltage of the output noise?
Show that a linear dependent current source controlled by a voltage appearing across an element in parallel with the dependent source is equivalent to a resistor. Determine the value of the resistance in terms of the parameters of the dependent so..
The circuit will have as inputs a minimum of two inputs; the binary equivalent of two decimal numbers of not greater than (10,000)10. The circuit will also produce a minimum of two outputs, the quotient and the remainder.
Convert function H(A, B, C) = (AB + C)(AC + B) into both the sum-of-products and product-of-sums forms. Obtain the truth table and express the function in both canonical forms: sum-of-minterms and product-of-Maxterms.
What observations can be made about a physical system that has both pole and zero locations that are not real-valued or complex conjugate pairs.
Find the magnitude of the electric field at all points in space both inside and outside the slab, in terms of x, the distance measured from the central plane of the slab. What is the field for x = 1.00 cm What is the field for x = 8.00 cm
A 2.5 meter long elastic cord is fixed at both ends. a) If the cord is vibrated at a frequency of 35-Hz, a n=3 standing wave is produced. with what speed do waves travel across the cord.
Model and simulate a 4-to-1 multiplexer using (a) Dataflow Modeling, (b) Behavioral Modeling, and (c) Structural Modeling. Use Modelsim and a VHDL test bench to simulate all the three models for a 4-to-1 multiplexer.
