Design a signal conditioning system to acquire and store a horizontal EOG biopotential. The bandwidth of interest is between 0.5 and 50 Hz and has peak amplitude of approximately +/-1 mV.-a. Design and draw a block diagram (not circuit) of the signal conditioning portions (everything before ADC) of your system.-b. Calculate the gain required to optimize you data acquisition into an ADC with desired input range of +/- 5 V.-c. If you have a 12-bit ADC DAQ-card, what is the resolution of your signal?-d. Is there enough voltage resolution to not require added gain on the biopotential?
A certain mixer is producing the following frequencies: 900 kHz, 700 kHz, 500 kHz, and 200 kHz. What are the two most likely input frequencies?
Show the design of a 2-1 Mux: (a) using a NAND/NAND implementation, (b) using a NOR/NOR implementation. Which would you prefer to build and why Assume that you have all variables and their complements available.
A digital communications system is being designed with the goal of transmitting 32 kbits/s over a channel having a bandwidth of 8 kHz. Determine (a) the number of encoding levels required and (b) the minimum signal-to-noise ratio required in the c..
A long wire carrying a 5.0 A current perpendicular to the xy-plane intersects the x-axis at x = -2.0 cm. A second, parallel wire carrying a 3.0 A current intersects the x-axis at x = +2.0 cm.
find an s-domain transfer function that has a specified frequency response and answer and discuss the following questions: 1. What determines the "order" of a transfer function 2. Given a transfer function, how is its frequency response calculated
The maximum flux density in the core of a 250/ 3000 volts, 50 Hz single phase transformer is 1.2 Wb/m2. if the emf per turn is 8 volt, determine (i) primary nad secondary turns (ii) area of the core
Design a parallel resonance circuit with resonance frequency of 30kHz and bandwidth of 20kHz and plot its frequency response.
Why can't a video signal such as an NTSC analog television signal be transmitted over a two km length of loaded twisted pair cable with a frequency range 300 Hz to 3,400 Hz? What is the bandwidth occupied by an NTSC video signal?
The Finite-Difference Time-Domain (FDTD) method is a computational electromagnetic technique for solving for the electric and magnetic fields in arbitrary spatial domains in the time domain
Two random variables have zero mean and variance of 16 and 36. Their correlation coefficient is 0.5. A). find the variance of the sum. B). find the variance of their difference C). Repeat (a) and (b) if the correlation coefficient is -0.5
Use the Z-transform of u[n] and properties of the Z-transform to find X(z). Verify that the expressions obtained above for X(z) are identical.
1. What is the force on a 10 cm wire carrying 1.0 A in a uniform magnetic field of 500 gauss 2. In the above example, if the current is in a loop of width 6.0 cm and the coil lies in the plane of magnetic flux, what is the torque on the loop
