The transistor parameters for the circuit in given Figure are:
hF E = 50, VB E (on) = 0.7 V, and VA = ∞.
Using nodal analysis, determine the closedloop small-signal voltage gain Av f = vo/vs at the midband frequency.
Vout=3.5v1 +(-1.5)v2 . The input impedances should be: input 1: 20k, input 2:∞.Youmay need to use 2 or more op-amps (inverting, noninverting,summing, differential, voltage follower...). Show calculations anda drawing of the op amps used.
A current of 4 A flows through a wire forming a "loop" circle of radius r. If the magnetic field in the center of the "loop" is 10 A, what is the radius along the "loop": a) if the loop consists of a loop of wire, b) if the "loop" consists of 20 t..
plot the magnitude and phase (bode plots) of the following transfer function in the frequency range of 0.1 to1000rd/sec. Fs=(s+10)(s+50)/200s2
If one page of memory can store 25 lines of characters with each line con- taining 80 characters, how many pages of information are there in 3 GBs of memory
salut a tous je suis eacutetudiant en fin de cycle option eacutelectromeacutecanique et je voulais savoir les
Read the binary number from the user and store it into a C string (i.e. char[ ]) The c string shall be able to accommodate a 32 bit binary number, note each digit in the binary number is a character, and there must be a null character at the end ..
A y polarized UPW motion in + x direction in free space has a maximum value of 20 (V/m) at a point x=1.5 (m) with the next adjacent minimum at x=2.75 (m) at time t=0 Obtain the wavelength and the frequency of the wave.
A differential amplifier has an open-loop voltage gain of 120 and a common input signal of 3.0 V to both terminals. An output signal of 24 mV results. Calculate the common-mode gain and the CMRR.
Suppose that data are stored on a 1.4-Mbyte floppy diskettes that weight 30 g each. Suppose that an airliner carries 10,000 kg of those floppies at a speed of 1000 km/h over a distance of 5000 km. What is the data transmission rate in bits per sec..
Two circular poles of the electromagnet, facing each other, both have a radius of R=0.1 m. The electromagnet is suddenly disconnected from its power source, and magnetic field decreases at a rate of 2.0 x 104 T/s.
Polarization in dielectrics. The space between two large parallel plates, separated a distance d = 0.1 mm is filled with a dielectric with relative permittivity of 4. The plates are connected to a 12 V battery.
How a transformer works and apply those rules to a transformer where the primary core cross-sectional area is twice.
