Consider the message signal m(t) = 20 cos(2πt) and the carrier signal c(t) = 50 cos(100πt). Write down the AM signal, and sketch the resulting AM signal waveform for 75 percent modulation.
explain the dilation, erosion, closing, and opening operations on a binary image B with a structured element S. ( you need to use the symbolic notion for the operators, but need not provide the precise mathematical definitions
How to find the damping ratio and undamped natural frequency given a 2nd-order differential equation.
A wave in free space has a wavelength of 12 cm. This wave reaches a material in which the transmitted wave has a wavelength of 8 cm. lEl= 10V/m and lHl= 100 mA/m. Find the frequency of the wave, along with the permitivity and permeability of the m..
Convert the value: $2103.25 using an IEEE standard 4 byte (32 bit) float floating point number representation. Identify every bit of the 32 bit number holding this record by first converting the number 2103.25 from decimal to binary
Consider a PCM-TDM system in which 24 signals are to be processed. Each signal has a baseband bandwidth of 3 KHz. The sampling rate has to be 33.3% higher than the theoretical minimum, and 8 bits are to be used.
Evaluate the component selection for the differentiator and integrator amplifiers and their impact on the mahematical equation for each. Items for you to consider and discuss are Do you observe any limitation factors for the component parameters an..
The heating element in a soldering iron has a resistance of 30-ohm. Find the average power dissipated in the soldering iron if it is connected to a voltage source of 117 V rms.
Overflow occurs when a result is too large to be represented accurately given a word size. Underflow occurs when a result is too small to be represented correctly (for example, a negative result while doing unsigned arithmetic.).
Consider the following signal y[n]; y[n] = X1[n+3] * X2[n] The signals X1 and X2 are defined as X1[n]=((1/2)^n) u[n] X2[n]= ((1/3)^n u[n] Determine the Z transform of y[n].
A GaAs device is dopeed with a donor concentration of 3*10^15 cm^-3, For the device to operate properly, the intrinsic carrier cconcentration must remain less than 5 percent of the total electron concentration.
A three phase 4.157kv 60hz power system serves a 2880kva load pf=.8 lagging. Draw the ac equivalent circuit with load impedance element equated. The load is delta connected. solve for all the current (6 total).
Determine which of these properties hold or don't hold for the following discrete time systems. Justify your answers. IN each example, y(t) denotes the system output and x(t) denotes the system input.
