The noise produced by a resistor is to be amplified by a noiseless amplifier having a voltage gain of 75 and a bandwidth of 100 kHz. A sensitive meter at the output reads 240 μV rms. assuming operation at 37°C, calculate the resistor's resistance. If the bandwidth were cut to 25 kHz, determine the expected output meter reading.
Determine the surface charge density on each conductor.
What is the symbol rate and what is the bandwidth occupied by the 16-QAM signal? The link must maintain a BER no higher than 10^-6. What is the minimum CNR in the receiver to meet this requirement?
Derive a system diagram for a frequency-modulated transmitter and explain the function of each stage and detect and reproduce (demodulate) the message signal. Measure the frequency of the detected signal and compare that with the frequency of the m..
Laplace transform of a pulse, Consider computing the Laplace transform of a pulse: use the integral formula to find P(s)
Explain briefly from what you notice about the digital output values in (a) why a digital output value of an A/D converter is rarely the exact same digital value as the analogue input value.
A 1 kHz sine wave signal with a power level -10 dBm is applied to the input of the amplifier. What is the power at the amplifier output?
If designing a computer configuration for use as a workstation for one specific application, what aspects of the software need to be considered as part of the design process?
