An aircraft flies from London to New York at a speed of 800 km/h. Assume New York is straight west of London at a distance of 5000 km. Use a Cartesian system of coordinates, centered in London, with New York in the negative x direction. At the altitude the airplane flies there is a wind, blowing horizontally from north to south (negative y direction) at a speed of 100 km/h.
(a) What must be the direction of flight if the airplane is to arrive in New York?
(b) What is the speed in the London-New York direction?
(c) How long does it take to cover the distance from London to New York?
Design a common emitter, voltage divider biased amplifier. The input signal has a frequency range of 20Hz to 50 kHz. The input voltage is 20mVpk, the beta is 300, and the source voltage is 12V.We need the ac output voltage (Vc) to be approximately 6V..
A power amplifier can be represented by a current source in parallel with a 200ohm resistance. An 8-ohm loudspeaker is connected to the power amplifier via an audio transformer so that maximum power is transferred to the loudspeaker. What must be ..
an fm transmitter delivers to a 50 ohm antenna a signal voltage of V(t)= 75sin(10^8 t+2 sin 10^3t) determine(a) carrier frequency (b) Intelligence frequency (c) modulation index (d) Total Power in FM signal

Consider a baseband transmission channel with a bandwidth of 10MHz. Which bit rates can be supported by bipolar line code and by Manchester line code
An electrical signal with the spectrum extending from 10Hz to600Hz is recorded on a tape recoorder at 10cm per second. It isplayed back at 60cm per minute. What would be the minimum samplingrate for the playback signal
he real power delivered by a source to two impedances, Z1=3+j4 ohm and Z2=10 ohm, connected in parallel, is 1100 W. Determine (a) the real power absorbed by each of the impedances and (b) the source current.
write a vba function called roll one of each that simulates the number of times you must roll six die at a time
A farmer owns two barns; one north of a creek and the other south of the creek. The farmer has a Cabbage, a Goat, and a Wolf. The Farmer needs to put each item in a barn every night. If the Cabbage and Goat are in the same barn
Design a second-order band-pass filter for a system with sampling frequency of 18 kHz that is tuned for f=5kHZ The filter should not have any sample delay (the numerator and denominator orders are equal)
Indicate which of the Two Wattmeter Method or Single Wattmeter Methods is the most accurate, giving reasons for your choice. Explain why there are variations between the theoretical and measured values of the tests
Design a combinational circuit that can detect whether a pattern of at least three adjacent 1s occur anywhere in an 8-bit input, and that outputs a 1 in that case. The inputs are a , b, c, d, e, f, g, and h, and the output is y.
