1. The impulse response for an ideal low pass filter with a pass band edge at omega1=0.5rads.
2. Design a low pass FIR filter for 10 kHz sampling, with a pass band edge at 2 kHz, a stop band edge at 3 kHz, and 20 dB stop band attenuation. Find the impulse response and the difference equation for the filter.
3. A voice signal sampled at 8 kHz must be filtered to eliminate elements outside the range from 300 to 3400 Hz before it is coded for transmission. Design the filter.
An ideal p-n junction diode has saturation current Is = 3e-15 A. Calculate the diode current.
Write down the principle of energy conversion and give an example for single and double excited system.
A ripple carry adder is made of full adder cells each having 1 unit of combinational delay. To convert a four-bit ripple carry adder into a four stage pipeline adder proceed as following.
Calculate the converter voltage VC1, reactive power, the converter phase current and modulation index.
Point charges of 5nC and -2nC are located at (2,0,4) and (-3,0,5), respectively. A. Determine the electric field at all points in space. B. Determine the force on a 1nC point charge located at (1,-3,7).
The ATSC broadcast television system used in the US transmits video signals at an average rate of 18.34 Mbps and employs 8-VSB modulation.
A pulsar lies 1000 light years from Earth. The average plasma concentration is 1 el/cc. Using the plasma dispersion relationship for group speed, what is the group delay between a pulsar pulse received at 1 GHz and at 800 MHz
The counter should increment on the rising edge of an input signal we'll call COUNT. Another input called CLEAR should have the effect of setting the counter to zero if CLEAR = 1 when COUNT is asserted.
Include worked solution, a discussion of any differences in the theoretical and measured values and screenshots that show your measurements and paste them into a document
What is the minimum donor doping required to convert Silicon into a conductor? What is the minimum acceptor doping required to convert Silicon into a conductor?
An OpAMP has a unity gain frequency (ft) of 10MHz and a slew rate of 10V/us and AVoc = 120dB at DC (f=0). Assume VCC = -VEE = 15 Volts.a. Approximate the cutoff frequency of the OPAMP itself. b.
The Hamming distance between two bit strings of the same length is the number of positions in which the strings have different bit values. For example, the Hamming distance between 1110 and 0101 is 3.
