4. A signal with power 7 mW is distorted by noise with power 0.002 mW. What is the signal to noise ratio (SNR) in dB?

Transform and draw the equivalent small signal circuit model using ONLY theHYBRID-PI model.

1.- The signal to noise ratio (S/N)dB for 3 different medicines turns out to be: (a) a negative value(b) zero(c) a positive valueWhat can be said about the signal strength and noise power in each case?In all 3 cases can the signal be recovered?

50. A signal x(t) = = sinc (150nt) is sampled at a rate of a) 100 Hz, b) 200 Hz, and c) 300Hz. For each of these cases, explain if you can recover the signal x(t) from the sampled signal.

Can you check if its correct: Draw and label the Frequency Response Plot of "GAIN vs Frequency" specifying the GAIN at: a. f = .1Fc --> gain = 9.95 b. f = Fc --> gain = 7.071  c. f = 10Fc  --> gain = 0.995

Design an ACTIVE band-pass filter for the midrange part of a loudspeaker so that the bandpass region is 400 Hz-2000 Hz (as defined by the -3dB points). Design the circuit so that the absolute gain is 2. a. Draw the circuit diagram and specify the resistor and capacitor values. Assume you can use either 100, 330, 500, or 1000 Ohm resistors and can select any value of capacitor. b. Sketch the frequency response (Gain [dB] vs. frequency (Hz)). Note that you will need to convert your gain to dB before plotting. Magnitude (dB) 15 10 5 midrange 12 1 -5 -10 -15 -20 -25 10 100 1,000 Frequency (Hz) 10,000 100,000
