Amplifier A has an input resistance of 1M Ω, an output resistance of 200Ω, and an open-circuit trans-resistance gain of 100MΩ. Amplifier B has an input resistance of 50Ω, an output impedance of 500 k Ω, and a short circuit current gain of 100. Find the voltage amplifier model for the cascade of A followed by B. Then, determine the corresponding trans-conductance amplifier model.
assume a transducer with a thevenin unloaded voltage of 5.0mv and a thevenin resistance of 20kilo ohms is connected
a new batterys voltage may be acceptable or unacceptable. a certain flashlight requires 2 batteries so batteries will
Draw a state diagram for an FSM that has an input X and an output Y. Whenever X changes from 0 to 1, Y should become 1 for two clock cycles and then return to 0, even if X is still 1. Develop both the Moore and Mealy machines.
An FH-BPSK signal modulated with 6kbps data has a spectrum bandwidth of 20 MHz. the BPSK signal is filtered allowing only two spectral components on either side of the carrier find the maximum number of hopping frequencies.
For a 12-bit linear PCM code with a resolution of 0.02 V, determine the voltage range that would be converted to the following PCM codes. (a) 1 0 0 0 0 0 0 0 0 0 0 1 (b) 0 0 0 0 0 0 0 0 0 0 0 0 (c) 1 1 0 ..
Fix the number of users K (to, say, 30) and the number of receive antennas nr (to, say, 5). Plot the symmetric rate with SDMA, orthogonal multiple access and the intermediate access scheme as a function of SNR (0 dB to 30 dB). How does the interme..
Three equal point charges Q form the corners of an equilateral triangle of side length "a". How much work is required to move one of the charges to a point half-way between the other two.
Signal w(t) is input to the filter. This signal is white noise, with PSD = N0/2. If we denote the filter output as n(t), what is the power in n(t) We input v(t) + w(t) into the filter, where v(t) = Ac cos(2pif0t). If Ac=4, what is the output signal..
The circuit shown in Figure P4.24 has been set up for a long time prior to t = 0 with the switch closed. Find the value of vC prior to t = 0. Find the steady-state value of vC after the switch has been opened for a long time.
Determine how you would design a planar shield to attenuate a far field signal by 15 db. Assumethat the incoming signal has a flat frequency spectrum from about 100 Hz to 10 MHz. Signalsabove 10 MHz and below 100 Hz can be considered to be negligible..
Calculate the inductive reactance per meter of a single-phase, 50-Hz, two-wire transmission line. Assume each conductor's radius is 6cm and the distance between the two conductors is 3m.
The command in AutoCAD can be a time-saver, particularly when you're working in an application where you want to move a door or windows within walls on a drawing and don't want to redraw the walls.
