Revise the night-light circuit of Figure 1.3 to include a switch that selects between activating the light when it is dark and activating the light during night-time hours. Assume there is a timer that produces a 1 output at night.
An inverter has a measured delay of 2ns. If five identicalinverters are connected in series, where the the first one isconnected to the last inverter, such that the voltage at the firstinverter will be an oscillate like a clock.
b) Calculate the armature current at start c) The motor is now used as a generator. Calculate the speed of the machine if the armature current is 80A and there is a 230V at the motor's terminals. Assume a constant flux.
The thermistors are to be sorted, with those having resistances between 8,000 and 15,000 ohms being shipped to a vendor. What fraction of these thermistors will be shipped
Estimate the equilibrium temperature rise and estimate the time constant - write an expression for the estimated curve (theta as a function of time) using the numerical results obtained in parts a and b.
Although this forms PNP and NPN transistors, the bias of the regions isdesigned so the junctions are reverse biased and the electric fieldeffects on the channel are supposed to control the MOS-FETtransistors operations.
what is the purpose of the compensating gauge?
An interconnect 60-Hz power system consist of one area with three turbine genrator units rated 1000,750,500 MVA respectively. The regulation constant of each unit is same R=0.05 per unit based on its own rating.
A silicon NPN bipolar junction transistor is to be used as an amplifier. What are the required bias conditions for this to occur If the emitter voltage is -3V, pick an acceptable base voltage and an acceptable collector voltage for the transistor ..
Determine the 8-bit sign-and-magnitude, 1's complement, and 2's complement representations for each of the following decimal numbers: +36, -84. (Note: Be sure to represent +36 as a positive number and -84 as a negative number.)
consider a continuos LTI system with step response given by ys(t) = tu(t) - (t - 2)u(t - 2). A. Determine the laplace transform X(s) of the input signal x(t) = u(t). B. Determine the Laplace transform Ys(s) of the step response.
A R-C high-pass filter contains a 1 µF capacitor and a 1k resistor. Suppose a single "square" voltage pulse of 5 V for 1 ms duration is applied to the input. Carefully and neatly sketch the resulting output, including numeric values, of output volt..
You are given two amplifiers, A and B, to connect in cascadebetween a 10-mV, 100-kΩ source and a 100-Ω load. Theamplifiers have voltage gain, input resistance, and output resistance as follows: For A, 100 V/V, 10kΩ, 10kΩ,respectively;
