An analog electronic signal is composed of three sine waves: 1 kHz @ 1 volt amplitude, 3 kHz @ 2 volts amplitude, and 4 kHz @ 5 volts amplitude (all voltage readings are peak-to-peak). The signal is digitized with 12 bits, spread over the range of -5 volts to +5 volts. For each sampling rate below, describe the frequency components that exist in the digital signal.Be sure to specify three things for each component: its digital frequency (a number between 0 and 0.5), its amplitude (in digital numbers, peak-to-peak), and its phase relative to the original analog signal (either 0 degrees or 180 degrees).
a. Sampling rate = 100 kHz.b. Sampling rate = 10 kHz.c. Sampling rate = 7.5 kHz.d. Sampling rate = 5.5 kHz.e. Sampling rate = 5 kHz.f. Sampling rate = 1.7 kHz.
Suppose an object with initial acceleration of 10 ft/s^2 is dropped from 300 ft. above the earth, how far would it travel in the first 2 seconds of its journey. Assume initial velocity is zero.
In a particular technology, a small BJT operating at vBE = 28VT conducts a collector current of 100µA. What is the corresponding saturation current. For a transistor in the same technology but with an emitter junction that is 32 times larger
It the resistors used are not ideal but have a ±5% manufacturing tolerance, what are the extreme output voltage and resistances that can result?
R1=1k ohms, R2=1.5k ohms and R3=3k ohms. Assume an ideal opAmp. Indicate the PEAK current in each of the resistors.
Design a DC power supply that provides -95v +/- 5v to a 2 amp load (energy absorber). The input source is a 100 volt peak sinusoid, 60 Hz. You may use any circuit element we've studied. State the values of all circuit elements
the signal shown below is a sine wave as it might be displayed on an oscilloscope. If it takes 40 msec. for the waveform to travel between the points shown by the arrow "B" below, what is the frequency of the waveform
Compute the value of ES(N) or OS(N) for a given number N. First, you use switch 0 to represent ES or OS. We use switch[0] = 0 to indicate the computation of ES(N) and switch[0] = 1 to indicate the computation of OS(N).
A 4 MHz time-harmonic uniform TEM plane wave that is traveling through a lossy nonmagnetic medium has an amplitude that attenuates by 20% for each meter of propagation. The electric field of the wave leads the magnetic field by 35°
A line charge of uniform charge density (l) forms a circle of radius b that lies in the xy-plane in air with the center at the origin. a) Find the electric field intensity E at the point (0,0,h) b) At what value of h will E in part (a) be a maximum
An aperiodic signal x(t) = 2sinc(2t) is multiplied by a periodic rectangular pulse train s(t) with fundamental frequency F0 = 4 Hz and the fundamental rectangular pulse given by p(t) = 1, 1/80 t 1/80 0, otherwise to obtain a signal xs(t) = x(t..
The purpose of this experiment is to setup the MASM assembler and linker. This will allow you to write assembly language source files and create executable code, such as .EXE and .COM files
Considering that the only parameters known are the input line-to-line voltage of 415V rms (f=50Hz), the firing angle (a= degrees) and the overlap angle (b=15degrees), calculate the Power Factor as seen from the input AC
