1.How do you compare PCM with PWM and PPM?2.A 8-bit ADC with 5 volt full scale voltage samples an analog signal at 1 kHz. Find the speed of the binary information at the output of the ADC.3. A linear PCM system uses an 8-bit ADC with 8 v full scale voltage. Find the dynamic range and the SQNR in dB.4.In a T1 PCM-TDM system, 24 signals all with the same bandwidth of 4 kHz are multiplexed after sampling at their Nyquist rate. If an 8-bit ADC is employed in this T-carrier system, find the speed of the digital multiplexed line. Assume 8 Kbps overhead for the T-carrier.5.For each of the following line codes, find the approximate required bandwidth of a T1 line.NRZ-LNRZ-MNRZ-SUnipolar-RZBipolar-RZAMIAnswers need to be in Word format.
3-singlephase 2 winding transformers, each rated 500 MVA, 13.8/199.2 kV, with leakage reactance Xeq = 0.10 per unit, are connected to form a three-phase bank. Winding resistances and exciting current are neglected.
The problem has two parts(a and b) and it asks: Find the power and rms value of each of the following signals: a) x(t) = 5 + Ccos(ωot+θ) b) x(t) = 2+7cos(1/2t+θ1)+3cos(2/3t+θ2)+5cos(6t+θ3)
The LM358 op amp can be a single or dual supply op-amp. This mean that it can operate with just a single supply i.e. + 5 volt or with dual supplies i.e. (+ and -) 5 volt supplies. With a inverting configuration with dual supplies (+5v and -5v) bei..
The boards have a weight of 40 lb, centered G. Determine the smallest angle Theta required for the man to support these boards, neglecting the man's weight and the friction between his shoes and the floor.
What happens to an ECG signal when a triggered average is applied I can see from the graphs that the peaks directly before and after the triggered peak become more and more blurry, but I don't understand
The speed of a separately excited DC motor is controlled by asingle-phase semiconverter . The field current, which is alsocontrolled by a semiconverter, is set to the maximum possiblevalue. The AC supply voltage to the armature and field converter..
The z-transform X(z) of a causal sequence x[n] has a zero at z1 = 0 and three poles at p1 = 3/4 and p2,3 = (1/2)(1 ± j). Determine the z-transform Y(z) of the sequence y[n] = x[n + 3], its pole-zero pattern, and its ROC.
Derivation of J-V relationship for p-n junction Steps: a) Write the excess electron concentration on the p-side as a function of position b) Write the excess hole concentration on the n-side as a function of position
