You are designing an Ethernet router/firewall/network address translatorusing an embedded linux operating system to control the device. One of the things that needs to be stored on a longterm basis in the device is the access log of IP addresses and port numbers that have attempted to access machines behind thedevice. Think of this device as the home router behind yourcable, DSL or FIOS modem. It is desirable to store at least256 IP addresses and port numbers, each requiring about 32 bytes of information. Contrast at least two of the options for thememory technology that might be employed for this access logstorage: static CMOS RAM, dynamic MOS RAM, Flash,electrically alterable ROM or mask programmed ROM.
A 40 H resistor, a 5 mH inductor, and a 1.25/xF capacitor are connected in series. The series-connected elements are energized by a sinusoidal voltage source whose voltage is 600 cos (8000t + 20°)V. a) Draw the frequency-domain equivalent circuit.
an amplifier with a 1 MHz bandwidth and a 20 micro-V input signal. The input noise = 1 micro-V, output signal = 6.0 mV, and output noise = 1 mV. Find (a) SNR at the input Pin = Pn(in)= K(T)BW= 1.38*10-23(290)1MHz= 4*10-15W
For the open-loop system \(G(s)=y(s)/u(s)=1/[s^{2}(s^{2}+400)]\) design the controller and estimator so that the closed-loop unit step response to a command input has a rise time tr
Determine the RMS generated voltage of an alternator used for a 50 Hz system if it has a flux per pole of 0.015 Wb, 72 turns per phase and a winding constant of 0.96
An 8mm thick brass [E=83 GPa; v = 0.33] plate is subjected to biaxial stress with sigma x = 180 MPa and sigma y = 65 MPa. The plate dimensions are b = 350 mm and h = 175 mm.
Two full charged 8A-Hr batteries are connected in parallel and supply power to a resistive load of 2.4 ohms. The open-circuit voltage of both batteries is 6.4VDC and the internal(Thevenin) resistances are 0.24 ohms and 0.28ohms.
Nyquist sampling rate condition and aliasing Consider the signal: X(t) = sin(0.5)/0.5t a.)Find the Fourier transform X(Ω) of x(t). b.)Is x(t) band limited. If so, find its maximum frequency Ωmax.
Please list the properties of Discrete Fourier Transform. Explain each property with an example to show what it means physically and explain the physical meaning of Z Transform
Fundamentals of Electric Circuits fourth edition: alexander, sadiku chapter 12 problem 12.29 A balanced three phase wye-delta system has Van= 120 angle 0 Vrms and Zdelta= 51+ j45 ohms. if the line impedance per phase is 0.4 + j1.2 ohms,
In addition, you have a 32-Kbyte Flash chip, a 16-Kbyte SRAM chip, and a 16 KByte DPRAM chip. You want to locate the FLASH chip right in the beginning of the address space, the SRAM chip just after it, and the DPRAM at the end of the address space..
The current in a single-loop circuit is 5.0 A. When an additional resistance of 2.0 O is inserted in series, the current drops to 4.0 A. What was the resistance in the original circuit
