A low-pass filter is shown in Figure 2. R = 1k
, C = 1μF
Construct a signal flow graph connecting input V1(s) and output V2(s) and showing internal signals I1(s),
I2(s), and V2(s).
Find T(s) = V3(s)
V1(s)
A new semiconductor has Nc = 1019 /cm3 and Nv=5 x 1018, and Eg = 2eV. If it is doped with 1017 donors (fully ionized), calculate the electron, hole, and intrinsic carrier concentrations at 627K.
Write general expressions for the electric and magnetic fields of a 1=GHz sinusoidal plane wave traveling in the +y-direction in a lossless nonmagnetic medium with relative permittivity er=9.
I started writing a program and need help. I need to be able to enter up to 15 numbers and output the minimum number, maximum number and the geometric mean.
Derive a minimum-cost realization of the four-variable function that is equal to 1 if exactly two or exactly three of its variables are equal to 1; otherwise it is equal to 0!
An AM signal is written as xc(t) = Ac (1+ µx(t))cos(2pi*fc*t) where fc is the carrier frequency, Ac is the carrier amplitude, µ is the modulation index, and x(t) is the baseband message signal. We assume that x(t) has absolute bandwidth W
Consider the penetration of a step potential function of height 2.4 eV by an electron whose energy is 2.1 eV. Determine the relative probability of finding the electron at the distance (a) 12 A beyond the barrier, and (b) 48 A beyond the barrier
An analog signal, containing frequencies up to and including 400Hz, is to be sampled at the minimum possible frequency, with a frequency resolution of 0.1 Hz. You are to find the sampling frequency, record length, and number of samples.
If you are now told that the material is copper and one cylinder has length 5 cms and radius 1mm, what is its resistance. You will have to locate the resistivity for copper and give me the reference source.
This will allow us to represent 256 numbers in that range, and there are only 6 integers in that range, so we'll be able to represent 250non-integral values, such as, perhaps, 2.5. Assume we will use a representation with 0xff representing 5 and 0..
a) How many ADC bits are required b) What is the maximum allowable noise at the amplifier output c) Design the analog amplifier/filter. A temperature transducer has the relationship: R= 200 + 10T where R is the O and T is in C(Celcius).
