Design a second-order band-pass IIR filter with center frequency of 450 Hz when the sampling frequency is 2000 Hz. In order to ensure the filter stability set the poles at 0.96 radial distant from the origin and to eliminate the filter output delay place two zeros at the origin.
Indicate the use of each memory in the microcontroller (HCS12). In other words, state which one is used for code, program variables, and variables that must remain when the power is turned off.
At the output of a two terminal DC network, when no load is attached , the voltage measured as 6 volts. When a load of 1 kiloohms is connected across output, the voltage at the output drops to 4 volts. Create a Thevenin Equivalent model of this ne..
What is the bandwidth occupied by this signal, and the noise bandwidth of the receiver for this signal? Find the BER at the receiver output and the average time between errors.
Perform a link budget for a 25-kilometer point-to-point microwave link in the 30 GHz band. Calculate the free space loss (dB), received power dBm), fade margin (dB), and Fresnel zone radius(m) given the following: Tx Power = 70 dBm
Calculate the approximate quantization S/N ratio in the baseband audio signal at the receiver output (after the DAC and LPF).
The average orbital radius of Neptune is 2.8 billion miles. Given that distance, how long on average does it take light from the sun to reach the planet Neptune in hours (Speed of light in English system = 186,282.4 miles/second)
The loop transfer function L(S) of a single-feedback-loop control system is given below. Sketch the Nyquist plot of L(jw) for w=0 to w=infinity, Determine the stability of the closed-loop system.
A digital communications system is being designed with the goal of transmitting 32 kbits/s over a channel having a bandwidth of 8 kHz. Determine (a) the number of encoding levels required and (b) the minimum signal-to-noise ratio required in the c..
Telephone channels have a bandwidth of about 3.1khz. do the following in excel. A) If a telephone channel signal to noise ratio is 1000, how fast can a telephone channel carry data?
Germanium is n-type doped at 5x1015 cm-3 at T=300 K. The dimensions of the Hall device are d=5x10-3 cm, W=2x10-2 cm, and L=10-1 cm. The current is Ix=250 A, the applied voltage is Vx=100 mV, and the magnetic flux density is Bz= 500
determine whether a three-bit number, a3, a2, a1, is equal to another number, b3, b2, b1, or if it is greater than that number. (We do not need an output for less than.) a. Show how the 7485 would be connected to accomplish
Suppose that an inductor is formed by N turns of a conductive wire wound around a magnetic material. The magnetic material forms a circular cylinder of radius r = 10 cm, and height h = 5 cm. The inductance of the inductor turns of N is defined as:..
