A beam consists of five planks of 1.5 X 6-in. cross section connected by steel bolts with a longitudinal spacing of 9 in. Knowing that the shear in the beam is vertical and equal to 2000 lb and that the allowable average shearing stress in each bolt is 7500 psi, determine the smallest permissible bolt diameter that can be used.
derive the BER (Bit Error Rate) of a 8-PAM (Pulse Amplitude Modulation) system in an AWGN (Additive White Gaussian Noise) channel.
The output voltage should be 5 V, but is ~1.25 V. This output voltage is independent of the power supply voltage. That is, no matter how high or low I set the power supply voltage, the output voltage is ~1.25 V as long as the input voltage is 50 mV.
Detailed Explanation to Op-Amp, A certain op-amp has an open-loop voltage gain of 100,000 and a common mode gain of 0.2. Determine the CMRR in dB.
Determine the value of Rw required to null the bridge when the applied weight on the scale is zero kg and Determine the bridge signal voltage ΔV when the applied weight onthe bridge is 999 kg
b) find nonhomogeneous solution with method of undetermined coefficient with constants evaluated c) combine homogeneous soluton with nonhomogeneous solution to form the general solution calculate the unknown constant in homogeneous part
In a particular technology, a small BJT operating at vBE = 28VT conducts a collector current of 100 µA. What is the corresponding saturation current. For a transistor in the same technology but with an emitter junction that is 32 times larger.
Given transfer function of dynamic system: T(s)= (2s^2 + 2s + 3) / (s^3 + 4s^2 + 6s + 10). write down state equation and output equation in Controllable Canonical Form and in Observable Canonical Form.
The voltage across the load must remain between 4.7 and 5.0 V for all values of load current. Design a voltage-divider network to supply the load. You may assume that resistors of any value desired are available.
What is the function of the enable control input of a tri-state buffer If the output of two or more tri-state buffers is connected to each other, what is the restriction on enable control input lines
silicon is doped so that 1 in 10000 Si atoms is replaced by phosphorous atoms. A) Knowing that only 30% of the phosphorous atoms donate electrons at room temperature (30% ionization) , determine the effective doping level and electron concentratio..
Design and provide the logic circuit of a 4 bit counter using the same techniques used to design synchronous sequential machines.The counter has three inputs: EN (Enable), OD (Order), and ST(Step). The initial output of the FSM is 0000.
Design a Double Sideband Amplitude Modulation (DSBAM) modulator and demodulator system using the SystemView software. The modulating wave m(t) = Amcos(2pifmt) and the carrier wave c(t) = Accos(2?fct) have the following parameters
