If a radio ran for 3 hours on a cheap battery rated at2Ah, how long will the radio run on a battery rated at 5Ah?
Design a Common Emitter amplifier with no bypass capacitor to obtain a voltage gain of -10 when Rin= 2k, Rload= 4k, VCC= 15V, VBE= 0.6V, and beta= 300. This amplifier requires an output swing of 4V peak-to-peak.
A control System with feedback has the following characteristic equation: s3 + (1 + K)s2 + 10s + (5 + 15K) = 0 The parameter K must be positive. When K is equal a single loop of wire with an enclosed area of 0.0900 m^2 is in a region of uniforfm mag..
Cradle to death is a typical lifecycle for any given application. The useful life of a particular application will vary based on advancements in a given discipline. It is critical to continuously seek and identify new ways to adapt technology.
Design a multi-stage audio amplifier for delivering an average power of 400 mW to a 16 Ohm speaker from a microphone that produces a 10 mV peak sinusoidal signal and has a source resistance of 1 kW. Use standard NPN QN2222 for your design.
Calculate the intensity transmission coefficient T1 for the following interfaces, assuming that the ultrasound beam is exactly perpendicular to the interface: muscle/kidney, air/muscle, and bone/muscle.
One side of the transformer bank is connected to a 120-kV transmission line, and the other side is connected to a three-phase load of 10 MVA at 13.2kV and 0.8 lagging power factor. Using the base in the tranmission line of 120-kV and 20 MVA.
1. Formulate the cost function in terms of autocorrelation values of the time sequence and filter weights 2. Derive Wiener-Hopf equations (in matrix form) 3. Determine the closed form solution for Wiener-Hopf equations (in matrix form)
Compensation occurs when a semiconductor is doped with both donor and acceptor dopants. Using the fact that n0p0=ni^2 (mass action law) and p0+Nd=n0+Na (charge neutrality assuming all dopants are ionized)
A 240kW 500V 1750 r/min separately excited dc generator has an overall efiiciency of 94%. The shunt field resistance is 60 ohms and the rated current is 5A. The I^2 R loss in the armature is 0.023 pu.
For the circuit of Figure the following parameters are given with Vcc = 18 volts DC: Rs = 0 ohm r pi = 1000 ohm Rb = 1750 ohms C1 = 10 microfarads gm = 50mS RL = 100 ohms Ce = 0.1 microfarads Re = 135 ohms C2 may be considered very large
determine the corediameter required for the fiber topermit its operation over the wavelength range 1.48 to 1.60um. calculate the new fiber core diameter to enable single mode transmission at a wave length of 1.30um.
Design a synchronous sequential circuit with one input line and one output line that recognizes the input string x = 1111. The circuit is also required to recognize overlapping sequence such that if the input string is x = 1101111111010
