Determine the Voltage ( Vm) across the electrical model of a cell membrane in a nerve cell
INa = - (Ik + ICl)
INa + Ik + ICl = 0
General Formulas for Voltage, Resistance, and Current:
E = IR R = 1 / g thus, E = I/g
The answer should be in terms of Ena, Gna, Ecl, Gcl, Ek, and Gk
An Si device is doped at 5*10 to the power of 16 cm-3. Assume that the device can operate up to a temperature where the intrinsic carrier density is less than 10% of the total carrier density. What is upper limit for the device operation
1.5V battery. Design a voltage divider to provide a voltage that is approximately 1/3 of the battery voltage. Use resistances in the kilo ohms range. Redesign your divider so that the resistors are in Mega ohms range.
With respect to sinusoidal signals, explain the difference between the way we normally define "amplitude" and the "amplitude" measurement on an oscilloscope. Also, How does the amplitude setting on a function generator relate to these
A load operating at 6400 Vrms draws 56 A at a PF of0.812 lagging. Find: (a) the peak current in amperes (b) the instantaneous power at t=2.5 ms assuming an operating frequency of 60 Hz
What is the minimum resolution in bits which would be required for an ideal ADC to have a dynamic range of at least 64 dB
To put this number into perspective, on June 20, 2002 the US national debt was $6.1e12, which is about $21,000 for each of the 288 million US citizens. What number when multiplied by the US national debt equals the cost to toast the bread.
If you have 1024 samples of a discrete-time band-limited signal sampled at a rate of 100MHz. what is the time period between samples. If you take a 2048 point FFT of the sampled signal, what will be the freuqency spacing between the output samples..
What is the lowest value of Vcc for which the BJT will always remain in the active region. Sketch Vl versus time for a Vcc slightly lower than this limit. Which BJT region(saturationor cuttoff) limits the output voltage swing.
Two LTIC systems have impulse response functions given by h1(t)=(1-t)[u)t)-u(t-1)] and h2(t)=t[u(t+2)-u(t-2)].a) Carefully sketch the functions h1(t) and h2(t). b) Assume that the two systems are connected in parallel.
The 1kHz signal is sampled at a rate of 4 k-samples/s and the sequence of samples is sent to a loud speaker. Using a diagram explain why high frequency tones are heard an what must be done to eliminate them.
a) Design an op amp circuit that will create an output voltage y(t) that is the solution to the differential equation y''(t) = 25 y, subject to the two initial conditions y(0) = 0.2 and dy(0)/dt = 0. You will need to use integrating op amps for t..
Given that you want to transfer a 3MB song by sending packets across an Ethernet link that has a MTU. of 1500 Bytes, answer the following questions. (for this question use 1MB = 1024KB, 1KB=1024Bytes)
