The sampling frequency in a DSP system is fs=16 kHz. Anti-aliasing filter used in the system is the second-order Butterworth filter with cutoff frequency of fc=4.2 kHz. What is the percentage of aliasing level at the cutoff frequency?
Suppose that the source charges of the two previous problems are present together. The potential at infinity is defined to be 0. a. Is the potential at the point (0.5, 0.5, 0.5) positive, negative, or zero b. Is the potential at (4, 4, 4) positive
Suppose that a voice signal normally occupies 30 kHz of bandwidth and has a signal-to-noise ratio of 20 dB. Spread-spectrum techniques are used to increase its bandwidth to 2 MHz. (a) What is the signal-to-noise ratio of the spread signal
The Per-cent impedance of a single-phase electric load is 2.5. The base power is 100KVA, and the base voltage is 12.47KV. a find the per-unit impedance of the load if 400KVA and 20 KV are selected as base values.
A power transistor for which Tjmax=180degrees Celsius can dissipate 50Watts at a case temperature of 50degrees. If it is connected to a heat sink using an insulating washer for which the thermal resistance is .6degrees Celsius/Watt
What is the value in Accumulator B after the execution of the code below ORG $2000 XYZ DC.B 0, 1, 2, 4 ORG $8000 LDY #XYZ LDAA #04 LDAB #02
Store the arrival times in memory locations starting from $1000.(Do this is in C. Store the results in an array and don't worry about the speci c location of the results.)
In a digital audio system, a digital to analog converter reproduces the analog voltage levels represented by the digital samples. This signal is inherently jagged with sharp transitions between each sample.
initially at a temperature of 17c and a pressure of 100 kpa air occupies a volume of 3.0 m 3 in a rigid vessel.a valve opens allowing air at 600 kpa and 17c to enter until equilibrium is reached final temperature is found to be 77c
1- find the inverse Laplace transforms of the following functions: A- f1(s)= 50(s+10)/((s+5)(s+20)) b- f2(s)= (2s^2)((s+200)(s+500)) 2- find the inverse Laplace transforms of the following functions and sketch their waveforms for β >0 : a- f1(s)= (β(..
Allocate this block to 3 different customers. Customer 1 requires a block at least 10 addresses, customer 2 requires 254 addresses, customer 3 requires 2 addresses. Give a possible allocation of these subnets using the CIDR prefix notation.
Operational amplifier - Finding the offset voltage, An operational amplifier has a gain of 20. The input voltage is 125mV and the input bias current is zero.
