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. Conventional NRZ-L encoding format is used. An extra bit is added to each frame for sync. Determine:
(a) Required sampling rate(b) Line speed(c) Minimum required bandwidth
the doping level of N-type semiconductor is ND = 5x10^19 cm^-3. Determine the room-temperature position of the Fermi level (with respect to the borrom of the conduction band) if the semiconductor is Si (Nc = 2.86x10^19).
Suppose that we wished to match an admittance using a double-stub tuner where the stubs are lambda/4 apart. For what range of admittance values can
Consider two signals that have the same frequency. When the amplitude of the first signal is at its maximum, the amplitude of the second signal is at half its maximum from the zero level. What is the phase shift between the two signals
Using coppers resistivity of 10.30 CM-olm/ft at +25 °C, find how long a 1 inch square bar of copper would need be to have a resistance of 1 at +20 °C
The isotope's half-life is 5 days. The average energy of the beta particles is 0.35 MeV with an RBE of 1.5. Ninety percent of the beta particles are absorbed within the patient's body and 10% escape. What total dose (in mSv) does the patient recei..
a) Design a minimum two-level NOR-gate network to realize the above function. b) Design a minimum three-level NOR-gate network to realize the above function.
If an AM signal has an un-modulated carrier voltage Vc=A volts(pk) and a load resistance RL of B ohms. How to calculate the Pc (Carrier Power) If the modulation index is known as m, how to calculate the Sideband Power (Psb)
A child is sitting on the outer edge of a merry-go-round that is 18 m in diameter. If the merry-go-round makes 5.4 rev/min, what is the velocity of the child in m/s
Write the VHDL architecture file for the Y(5) output only for a 8-to-1 demultiplexer. The inputs are D, the selects S0-S2, and the ouputs Y(0)-Y(7). the select lines are bit_vector types, the data is bit type and the outputs are bit_vector types.
The terminals of an electrical device are labeled a and b. If vab = 10V , how much energy is exchanged when a charge of 3 C moves through the device from a to b. Is the energy delivered to the device (i.e., device dissipating or storing energy).
Find the sample space for the following experiment: Drawing bolts from a lot of 20, containing one defective D, until D is drawn, one at a time and assuming sampling without replacement, that is, bolts drawn are not returned to the lot.
An op amp wired in the inverting configuration with the input grounded, having R2=100k-ohm and R1=1k-ohm, has an ouput dc voltage of -0.4 V. If the input bias current is known to be very small, find the input offset voltage.
