Five periods of the signal s(t)=sin(2500pi*t) are sampled at a sampling frequency of 4000 Hz. a. Does this sampling frequency meet the Nyquist requirement for the signal? b. How many samples are collected?
Derive the transmission and reflection coefficients for the case of tunneling through a square potential barrier with 0
Calculate the de Broglie wavelength, for: (a) An electron with kinetic energy of (a) 1.0 eV, and (ii) 100 eV. (b) A proton with kinetic energy of 1.0 eV. (c) A singly ionized tungsten atom with k in.
This solution shows how to work from a given circuit implementation (a J-K flip flop circuit design) to derive the Boolean Logic and in so doing so simplify such logic using Boolean Algebra rules
assuming XTAL=11.0592 MHz,write a program to genrate a square wave of 20 Hz frequency on pin2.3?
If each gold atom donates one electron to the gold matrix at room temperature, estimate the electron concentration of gold. Is gold a conductor?
a plane wave is obliquely incident onto the planar interface between mismatched, lossless, nonmagnetic, uniform media, yet undergoes no reflection. If incidence is at 54 degrees to the normal, at what angle to the normal does the transmitted wave ..
Create a block diagram of the electronics of the proposed vehicle. Include enough detail on each components and number of wires between each subsystem.
A cell phone transmits voice signals on a carrier. the transmissions lie inbetween 900MHz to 900.03MHz. What minimum sampling rate should be choosen so that the transmisions will be recoverable from the digital samles
The resistance of the shunt field winding and the resistance setting of the shunt field rheostat of a separately excited generator are 10.26 ohm and 14.23 ohm respectively. The field circuit is connected to a 120-V DC source.
A computer employs RAM chips of 256 x 8and ROM chips of 1024 x 8. The computer system needs 2K bytes of RAM, 4K bytes of ROM, and four interface units, each with four registers. A memory-mapped I/0 configuration is used.
A silicon diode with a breakdown voltage of 2000V that is conducting a forward current of 2000A is turned off with a constant diR/dt=250 A/s. Roughly estimate the time required for the diode to turn off.
