Problem 5: Voltage Amplifier with Transducer A voltage amplifier is used to amplifier a transducer signal as shown in the schematic below. The transducer signal is a sinusoidal voltage with amplitude VA. The transducer has a series resistance Rsig, and the amplifier has an input resistance Rin. Determine the output voltage amplitude. schematic: Vin Vout ----Rsig---- (+) | Rin /\+\ Avo*Vin \-/ (-) Vsig | gnd gnd gnd You have no prior attempts on this problem. You can work on it now or type 'skip' to move on to the next one. VA = 10 mV === 4 Given Values (in workspace) === Rsig = 50 Ohm Rin = 1 kOhm Avo = 10 V/V

If the father of the woman who was the mother of the colour blind child had normal vision how did the child end up as colour blind? Colour blindness is a recessive gene carried in the X - chromosome. A man with normal vision has a child with a woman that has normal vision. They have a child that is colour blind. The grandfather of the child was a carrier of the gene but did not have the condition. The grandmother of the child had to be a carrier of the gene. The mother of the child could not of had the gene as she had normal vision. The father of the child gave the colour blind gene to his child.
