1. An AM signal has an unmodulated carrier voltage VC = 10VP, a load resistance of RL = 10, and a modulation index of m = 1. Determine:
A. PC and PSB
B. Total power in the AM signal
2. You are tuned to an AM station at 1200 KHz. Write down the frequency components of the received AM signal.
The following functions describe the oscillations in electric circuits and the vibrations of machines and structures. Plot these functions on the same plot. Because they are similar decide how best to plot and label them to avoid confusion.
Current Pulses over a Twisted Pair Telephone Line, A twisted pair telephone line has a constant attenuation between 0 Hz and 3300 Hz and linear phase shift with frequency
3) What factors started the decline in the nuclear power industry, and what events essentially ended new construction of nuclear power plants 4) What are three advantages of using AC power over using DC power

the worker's safety harness D-ring is attached to a 12-foot shock absorbing lanyard that is securely fastened to the structure at a point 40 feet above ground level. Does this arrangement violate OSHA standards for fall protection? Explain.
Design a VDHL file controller to operate two separate sets of three traffic light signals, one for each direction. Use eight LEDs as shown in to represent the outputs. The Time in This State can be met in several ways.
assume single pulse of ampltude (+1) transmitted through a band-limited noise free channel.The sampled output of the reciever filter is y y= [0.32 0.98 0.25] Determine a three-tap adaptive linear equalizer when the recieved power is 0.15W.
A 120 V separately excited DC Motor is operated at a fixed field current. It has an armature resistance Ra = 10 ohms, and a machine constant K = 0.1 V/rpm. The armature current is 0.5 amps with no load, and 3.0 amps at full load.
Consider the interval [0,30]: y[n+2] - 0.6y[n+1] - 0.16y[n] = 5x[n+2]. a.) Find zero-state response if the input is x[n]= 4^(-n)u[n] b.) Find zero-state response if the input is x[n]= cos(2npi/6)u[n]
A digital signaling system is required to operate at 9600 bps. If a signaling element encodes a 8-bit word, what is the minimum required bandwidth of the channel?
a) Given that the refractive index of water is about 1.33, what is the polarization angle for light traveling in air and reflected from the surface of water b) Consider a diver in sea pointing a flashlight towards the surface of the water.
The stepped cylindrical tank is initially filled with liquid water at STP to a height H1. Subsequently, a plug at the bottom of the tank is removed to allow water to flow from the small hole of diameter d. The velocity v of the flowing water
