Suppose the quadrature up conversion mixers in a GSM transmitter operate with a peak baseband swing of 0.3 V.
If the TX delivers an output power of 1 W, determine the maximum tolerable input-referred noise of the mixers such that the transmitted noise in the GSM RX band does not exceed -155 dBm.
A system samples a sinusoid of frequency 850 Hz at a rate of 250 Hz and writes the sampled signal to its output without further modification. Determine the frequency that the sampling system will generate in its output.
Three light bulbs are connected in series to a 100-V battery in a circuit. Each light bulb dissipates 30W, 40W, and 50W, Respectively. Find the current (I) through the light bulbs.
Implement the circuit with a block diagram decoder (you don'tneed to show the internal implementation of the decoder) and OR gates only. A combinational circuit is specified by the following three Boolean functions
D rectangular resonator. Write a 3D FDTD algorithm using Equations (4.18) and (4.19) in a 100 × 50 × 20 m box with perfectly conducting walls.
Draw this electric circuit and the circuit can be composed of resistors, inductors, capacitors and opamps only. Then verify your circuit for any arbitrary DC voltage used instead of Vin by PSPICE.
1 a discrete memoryless source has a symbol alphabet of a 10. determine the upper and lower bounds on its entropy. 2
What does "transfer function" of a filter represent What do the Amplitude Ratio (Gain) and Phase Angle represent What are the key differences between a real filter (the RC circuit) and an Ideal Filter (please read LPF Treated as an Ideal Filter)
Convert the source into the phasor domain and then do a source transformation into a current source in parallel with an impedance.
given appositive number α, determine the constants A,B,C such that the iteration converges locally to 1/α with orderp= 3. (this will give a cubically convergent method for computing the reciprocal 1/α which uses on addition, subtraction, and multi..
Because A - B = A + (-B), the subtraction of signed numbers can be accomplished by adding the complement. Subtract each of the following pairs of 5-bit binary numbers by adding the complement of the subtrahend to the minuend. Indicate when an over..
A capacitor is charged to 100 V and is then disconnected. Leakage reduces its voltage to 35 V in 45 minutes. Estimate the additional time required for the voltage to drop to 8 V. The leakage is represented by a resistance in parallel with the c..
