Assume that your grades will be lower than expected at the end of the semester, and write out a strategy for recovering from these low grades.
The channel bandwidth for the analog AMP's system is restricted to BW= 30 kHz. Determine the noise floor (in dBm) for its mobile receivers assuming all receivers have a noise figure of 10 dB.
A receiver with a synchronous detector receives a barely intelligible message since the (s/n)d =4 db . it has been determined that the transmitter has ST= 100 W , μ = 0.9 and SX=0.5. What is the minimum value of ST if envelope detection were used.
A parellel plate air capacitor has plates of 1500cm2 seperated by 5mm. if a layer of dielectric 2mm thick and relative permittivity 3 is now introduced between the plates, then the new seperation in mm between the plates, so that the capacitance valu..
Telephone channels and PCM analysis, The analog to digital converter (ADC) used in a telephone system outputs 8 bit words. The digital words are transmitted as a serial stream to form a PCM voice signal
The controlled variable in a closed-loop system is the direction of a robot arm. Initially, it is at 40o; then it is commanded to go to 22o. What is the error when the arm position is at 15o
A three-phase, four-pole, 50-hp, 480-V, 60-Hz, Y-connected induction motor has the following parameters per phase: r1 = 0.10 , x1 = 0.35 , r2' = 0.12 , x2' = 0.40 . It is known that the stator core losses amount to 1200 W and the rotational lo..
A uniform plane wave propagates from one dielectric into another at normal incidence. Find the ratio of the dielectric constants such that the magnitudes of the reflection and transmission coefficients are both equal to 0.5.
Suppose the circuit is designed for a nominal gain of 2.00 but the R1 and R2 suffer from a mismatch of 5% (i.e., R1 = (1 ±0:05) R2). What is the actual voltage gain?
Calculate the SNR due to quantization using the MATLAB program.
A material has a dielectric constant of εr=3.0 andhas an atomic density of 1028 atoms per cubic meter. Ifonly two electrons in the outer orbital shell will distort with anapplied E-field, and both electrons follow the same orbital path asa pair
When the input returns 1the sequence stops were it was left off. The output should change only on a rising clock edge. Make 000 the initial state. Assume an implicit rising clock is ANDed with every FSM transition condition.
Three parts of asingle-phase electric system are designated A,B and C and areconnected to each other through transformers. Neglect transformerresistance and magnetizing current. The transformers are rated as follows
