A new 1.5-V AA battery delivers 40 kJ of energy during its life time. How long will the battery last in an application that draws 10 mA continuously. Assume the battery voltage is constant.
A car battery with a 14.2 V emf and aninternal resistance of 0.0380 is beingcharged with a current of 51.5 A. (a) What is the potential difference across its terminals
find the Laplace transformation to find the v(t) that satisfies the following firs-order differential equation : a) 500 dv(t)/d(t) +2500 v(t)= 0 , v(-0)= 100V b) dv(t)/d(t) +200v(t)= 400u(t)V , v(-0)= -100V
What effect do internal capacitances in the transistor model have on practical performance of a real system? How would you use these model values to predict system performance?
Consider a particular communication system that the threshold is 1.5. If the signal energy falls below the threshold, the system is in the outage state. What is the outage probability P?
The system works as follows. When the main program starts to run, the microprocessor commands the A/D to convert. The microprocessor then sits in a dummy loop until the A/D interrupts, after it has completed the conversion and data is available.
assuming k>0 what is steady state the response of the above system due to an input of the form , x(t) = 2sigma(t)+u(t). where sigma(t) denotes unit impulse function and u(t) denotes unit step function
Design a state graph and state table for a Moore sequential circuit that has two inputs (X1 and X2) and one output (Z). The output begins at 0 and becomes 1 when X1 = 1 and X2 = 1, either concurrently or one after the other
The resistance, inductance, and capacitance in a parallel RLC circuit are 2000 Ohms, 250 mH, and 10 nF, respectively. a) calculate the roots of the characteristic equation that describe the voltage response of the circuit.b) Will the response be over..
Consider two continuous signals f(x, y) and g(x, y) that are separable, show that their convolution is also separable. Show that the 2-D Fourier transform of the rect function is the sinc function.
A cable technician tested the signal-to-noise ratio on the curb as 20 dBm. This means, if the noise power is at 1 mW, then the signal power should be 20 dB higher then that. If the noise power is 20 mW
MOSFET Amplier Sketch the 4-resistor bias network for an amplier with an n-channel enhancement-mode MOSFET, with R1 = 1Mohm ; R2 = 1:5Mohm ; RD = 75kohm ; Rs = 39kohm ; K = 25microA/V2 ; VDD = 10V and Vto = 1V.
Sketch the baseband signals for the two users when user 1 sends the bits 011, and user 2 sends the bits 101. Add the signals for the first bit only, and show that the output of the correlator for user 1 is -4, corresponding to a 0
