the hd cable signal send out is usually ranging between (1-25mv), with the frequency range from 1000Hz- 20Khz. An amplifier will gain 46 db will boost the signal before sending it through the cable connection. Signal will travel through 2 cable segments, each will deteroriate the signal by 1/100. To maintain the signal level, at the end of each cable segment a repeater was placed with gain + 20 db. Arriving at the location, signal is then splits to 20 houses which cause 60 db deteroriation. Calculate and design the appropriate amplifier needed to maintain the signal (max) 5V at the house.
A temperature sensor has a static transfer function of 0.15 mV/C° and a time constant of 3.3 s. If a step change of 22° to 50° C is applied at t=0, find the output voltage at 0.5 s from t=0s to t=10s. What is the indicated temperature at these tim..
1.The signal is 10 sin (pi 500t +30deg). The amplitude of this signal is 2.The signal is 2 sin(pi 1500 t + 60deg). The frequency of the signal is 3.The signal is 5 sin(4 pi 800t - 80 deg). The phase of this signal is
Sam (75 ) takes off up a 50--high, 10 frictionless slope on his jet-powered skis. The skis have a thrust of 200 . He keeps his skis tilted at 10 after becoming airborne. How far does Sam land from the base of the cliff
Capacitance can be altered by immersing part of the two wire line into a different medium. (a) What is the capaccitance per unit length in F/m of the transmission lines. You must explain your reasoning and show the equation you used.
A single phase 220V system draws a current of 15A at a lagging power factor of 0.8. Calculate the value of a capacitor that can be used to improve the power factor of this system to 0.95 lagging.
A 4KHz audio signal is transmitted by using a PCM system and the quantization level, L is 256. Find transmission bit rate.
A 10kVA, 200/400V 50Hz single-phase transformer gave the following test results. O/C test: 200V, 1.3A, 120W, on l.v. side. S/C test: 22V, 30A, 200W on h.v. side. (a) Calculate the magnetizing current and the component corresponding to core loss
Write the formula for the maximum clock frequency for an n-bit synchronous parallel binary counter. Beyond what value of n is your formula no longer valid. let Ttq denote the propagatoin delay from T to Q in a T flip-flop.
The steady-state electron distribution in silicon can be approximated by a linear function of x. The maximum electron concentration occurs at x = 0 and is n(0) = 2.0 x 1016cm-3. At x = 0.012cm, the electron concentration is 5.0 x 1015cm-3.
Consider two Functions F = E(1,2,3,5,7,9) and G = E(0,5,7,8,9,11,13,15) a) Use K-maps to minimize the function Fb) Use K-maps to minimize the function G c) How many total terms and literals are present in the two equations
The dielectric materials used in real capacitors are not perfect insulators. A resistance called a leakage resistance in parallel with the capacitance can model this imperfection. A 150-F capacitor is initially charged to 100 V.
A new type of Schottky diode is optimized for low-voltage applications. It has typical forward voltage drop of 0.2 V, but its leakage current can be as high as 80 mA. It is being considered for a 12 V to 2.5 V converter with 50 W load.
