A 2-V-peak sine wave signal is converted to digital form by a 12-bit ADC that has been designed to accept signals ranging from -5V to +5 V. (In other words, code words are assigned for equal increments of amplitude for amplitudes between -5V and +5V.)
a. Determine the width ? of each quantization zone.
b. Determine the rms value of the quantization noise and the power that the quantization noise would deliver to a resistance R.
c. Determine the power that the 2-V sine wave signal would deliver to a resistance R.
d. Divide the signal power found in part (c) by the noise power determined in part (b). This ratio is called the signal to- noise ratio (SNR). Express the SNR in decibels, using the formula SNR dB = 10 log (Psignal/Pnoise).
What is the starting current of this machine if it is started by connecting it directly to the power supply VT ? How does this starting current compare to the full-load current of the motor?
What is the maximum value of N0 for an FM cell phone whereby ST=
At a certain radian frequency, ω, a 25 Ohm resistor in parallel with a capacitor, C, has the same impedance as a 20 Ohm resistor in serires with a 0.01 F capacitor. What are the values of ω and C.
Using VDD = 1 .8 V and a pair of matched MOSFETs, design the current-source circuit to provide an output current of 200μA nominal value. To simplify matters. assume that the nominal value of the output current is obtained at Vo ≈ VGS.
A meter being used for a 2-wire resistance measurement has an internal current source of 1 mA. If the meter's test leads have equal resistances of 0.06-ohm, what is the measured resistance for: A resistor of actual value 0.5-ohm
Assume the z0 is in the far field and derive an expression for the strength to return as a function of angle. Make approximations where appropriate and do not forget the sidelobes.
The frequencies of the tones are 100 Hz, 300 Hz, and 450 Hz. The sampling rate is 1 kHz. Describe a low pass, a band pass, and a high pass filter that could be used to detect the individual tones.
