A system samples a sinusoid of frequency 850 Hz at a rate of 250 Hz and writes the sampled signal to its output without further modification. Determine the frequency that the sampling system will generate in its output.
Baseband digital trnamission and multi level coding, A baseband digital data link transmits polar binary NRZ current pulses at a rate of 1.0 Msps. The link uses ideal RRC filters with roll off factor r = 0.5.
the SABER instrument aboard the TIMED satellite orbits the earth in a sun-synchronous polar orbit 625 Km above the earth. each of the 10 SABER focal plan detectors is 0.14mm high by 2.0mm wide. the focal plane array is 4.882*4.882mm in size
Create a bandpass filter with cutoff frequencies of 100-1k, attenuate by at least 3db at desired frequency(100-1k) and at 60Hz attenuate by 10 db. Resistor, Capacitor, Inductor, and Op-amps can be used.
A cable technician tested the signal-to-noise ratio on the curb as 20 dBm. This means, if the noise power is at 1 mW, then the signal power should be 20 dB higher then that. If the noise power is 20 mW
Vary as square root-application, The frequency f of vibration of a wire varies directly as the square root of the tension T of the wire
A transmission line with no loss, with Z0= 60 ohms, is operated at 60MHz. The velocity on the line is c. The line is soldered to a ground connection at z=0. Find the input impedance into this line at z= -1.25 meters
The open circuit test on a single-phase 15kVA, 7500/480 V, 60 Hz distribution transformer yielded the following: V = 7500V; I = 0.2006A; P = 180W Calculate the core parameters RC and XM and the magnetizing current IM.
Design a parallel resonance circuit with resonance frequency of 30kHz and bandwidth of 20kHz and plot its frequency response.
The system uses a 7-cell reuse pattern. If the offered traffic per user is 0.03 Erlangs and the average number of calls per hour per user is 1.5, for an Erlang-C system with a probability of delaying a call being 5%, calculate the traffic load per..
"Divide by 3 clock with 50% duty cycle" is the most commonly asked ASIC design question. This solution gives a simple design in which only 1 counter is required which works only on positive edge of the clock.
What is the system's Nyquist sample rate if ω0 = 1000/(2π) rad/sec.?
he real power delivered by a source to two impedances, Z1=3+j4 ohm and Z2=10 ohm, connected in parallel, is 1100 W. Determine (a) the real power absorbed by each of the impedances and (b) the source current.
