Build and test the operational amplifier summing circuit you designed for the Prelab using 741-type op-amps. Use VA = 2 V and VB = 3 V with power supply rails of ±18 V. Ask your lab instructor to give the correct pin-out of the 741 if necessary. To obtain the approximate input voltages, use the voltage divider circuit shown below; if you don't have 30-ohm resistors available, use two 15-ohm resistors in series for each. Some component "tweaking" may be necessary if your particular circuit is an appreciable load on the voltage divider. When connecting the bipolar power supply, make sure the center terminal is connected to the same common ground as the rest of the circuit; otherwise, it will not work properly. What is the output voltage? Does your circuit achieve the mathematical expression Vout = 2VA + 3VB? Use the space provided for mathematical computations if necessary.
List three standard socket calls that you would expect every connection-oriented server to invoke that would not normally be invoked by any client. Briefy indicate why a typical client would not need to invoke these calls.
A uniform plane wave propogates in the positive z direction with a frequency of 20 MHz. A probe is at z=0 m measuring the phase to 98 degrees and another probe at z= 2 m measures the phase to be -15 degrees what is the relative dielectric constant..
determine the transfer function of a 4th order lowpass butterworth filter with a 3-dB cutoff frequency of 3.4 kHz and passband gain=1. Design the circuit using MFB topology. Design two sections with an order of 2.
During four consecutive clock pulses, a sequence of four values of the x signal is applied. Derive a state table for the FSM that produces z = 1 when it detects that either the sequence 1001 or 0111 has been applied; otherwise, z = 0. After the fo..
A balanced three-phase inductive load is supplied in steady state by a balanced three-phase voltage source with a phase voltage of 120Vrms. The load draws a total of 10kW at a power factor of 0.9.
a. A load consumes 150kW with a power factor pf = 0.7 (lagging). If the load current is 240A (RMS), find the load voltage. b. An industrial plant has an inductive load which consumes 10kW of power from a 220VRMS line.
stochastic message signal, m(t), is transmitted down a (noiseless) cable channel by PCM, using an 8-bit code. If the ambient signal is equally likely to lie anywhere between its two extremes, (+/- mp), calculate the ration of the mean squared sign..
