what effect does the diode barrier potential have on the difference between the peak input voltage and the peak output voltage? Explain
The result of part a) is the upperlimit. However, as a practical matter, better error performancewill be achieved at a lower data rate. Assume wechoose a data rate of 2/3 teh maximum theoretical limit. How many signal levels are needed to achieve ..
A p-channel MOSFET with a threshold voltage V,p = -0.7 V has its SOUTce connected to ground. (a) What should the gate voltage be for the device to operate with an overdrive voltage of Ilor! = 0.5 V
How much current must a logic output source, in order to maintain an output voltage of 2.5V when driving a 5K resistor connected to ground.
Assume initially that no inputs have been seen and create a special initial state with output 0 to start the Moore machine. Draw a state graph for a Moore machine (minimum number of states is 6).
A base stationcellular communicationsystems lossless antenna has a maximum gain of 16 dB (above isotropic) at 1,900 MHz. Assuming the input power to the antenna is 8 watts, what is the maximum radiated power density (in watts/cm^2)
A voltage source Vs = 10 Cos(10^3t - 90 degrees) v, a resistanceFind the max instantaneous power delivered by the source, dissipated by R, and absorbed by L. What are the smallest instants (t > 0) at which these maxima occur.
Two DTEs are communicating via modems and RS-232C interfaces over a half duplex link. Data transmission is one directional with each message of length M. After a message is transmitted, the sender waits for a CTS message.
A square of charge Q lies in the x-y plane with sides of length L, centered at the origin. A point P lies a distance z above the origin along the z-axis. Calculate the E-field at P. Put the final answer in terms of Q, not the charge density.
Consider the following function of t, f(t)=1/a[u(t-T0)-u(t-T0-a)]. Here both T0 and a are positive numbers. If you pick some value for T0 and a you discover that you have a rectangular pulse starting at T0 having width a and height 1/a.
Determine whether the following discrete-time systems are causal or noncausal, have memory or are memoryless, are linear or nonlinear, are time invariant or time varying. In the following parts, x[n] is an arbitrary input and y[n] is the response
