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?
Finding peak amplitude, frequency, and spectrum shape, b. A signal generator outputs a unipolar square wave with a period of 0.50 ms and an amplitude of 2.0 V. The output of the generator is passed through an ideal band pass filter that has a pass..
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.
You are required to determine that this next generation transmission system will require a spectral efficiency of 5 bits/sec per Hertz.
The signal m(t)=6sin(2*pi*t) volts is transmitted using 4-bit binary PCM system. The quantizer is of the midriser type, with a step size of 1v
Laplace transform of a pulse, Consider computing the Laplace transform of a pulse: use the integral formula to find P(s)
Calculate the approximate quantization S/N ratio in the baseband audio signal at the receiver output (after the DAC and LPF).
Using 4-bit numbers to save space, multiply 3ten x 4ten in binary.
A telephone switching board can handle 120 phones. Assuming the following, and determine the outgoing traffic intensity and the number of channels
The aim of this experiment is to develop a bipolar transistor amplifier with a voltage gain of minus 25. The amplifier must accept input signals from a source impedance of 1 kW and provide an undistorted output amplitude of 5 V when driving a 560..
Consider a chip design using 10 mask levels. Suppose that each mask can be made with 98% yield. Determine the composite mask yield for the set of 10 masks.
Analysis of link budget DTH QPSK Satellite link, A direct-to-home satellite television system uses a geostationary satellite in orbit above the equator at a longitude of 109 degrees west.
What is the shape of the spectrum of the signal? What is the extent of the spectrum in the frequency domain? What is the unit that is applied to the magnitude of the spectrum?
