The effective or root-mean-square value of a time-varying currentis, by definition, equal to the direct current that produces the same joule heat as the alternating current. That is, the Irms value of an oscillating current is found by calculating the average power in the resistor and equating it to the direct-current power. Based upon this definition, calculate Irms for square-wave currents.
There are two charge distributions: one in a infinite plane of charge in x=-2 with a surface charge density of 3mC/m2, abd a infinite line of charge with a linear charge density of -3mC/m that goes through the points A(0, 0, 3m) and B(0, 3m, 0).
Each limit switch has one normally open, NO, contact and onenormally closed, NC, contact. Two control relays, CR1 and CR2, areused in the gate control circuit. These relays have two NO contactsand two NC contacts. A NO pushbutton START switch is u..
The loop transfer function of a single-loop negative feedback system is: L(s) = Gc(s)G(s) = K(s + 2.5)(s + 3.2) / (s2(s + 1)(s + 10)(s + 30)) This system is called conditionally stable because it is stable only for a range of the gain K
digital radio link has a bandwidth of 8 kHz and support a transmission of 87 kbps. According to Nyquist how many bits per symbol are required to modulate the signal Remember to use an integer number of bits.
1) Design inverting amplifier circuits with gains of 1, 10,and 100, and show the component values. 2)Calculate the inverting amp output at each gain setting for V2 is1.0Vpp at 100Hz
A Widlar Current Source is designed to limit the load current to the reference current by using a resistor at the emitter end by:I(load)*R(Emitter)=Vt ln (I(ref)/I(load))=VBE(Ref)-VBE(Load)
A transmission line is specified by the following, while operated at omega w=6*10^8 rad/s, L'= 0.4*10^-6 H/m, C'=40*10^-12 F/m, G'=80*10^-6 S/m, and R'=20 ohms/m. Find the attenuation rate after a wave propagates 10 meters on this line.
For example, if the time given is 10213 seconds, the function will give back 2 hours and 50.22 minutes. The function shall not print the results to console, but instead pass them back to the calling function.
Three amplifiers with power gains of 15, 22, and 7 are cascaded. The input power is 120 µW. What is the output power of the final amplifier stage
