For each amplifier in Figure 12-73, determine the closed-loop gain and bandwidth. The op-amps in each circuit exhibit an open-loop gain of 125 dB and a unity-gain bandwidth of 2.8 MHz.
A certain internally compensated (dominant pole) op amp has a dc gain of 200,000 and 3 dB bandwidth of 5 Hz. Sketch the Bode plot of the magnitude of the open loop gain to scale.
Assuming the x- and y-axes to be directed eastward and northward, respectively, find the expression for the propagation vector of a uniform plane wave of frequency 15 MHz in free space propagating in the direction 30° north of east.
Determine whether the foolowing discrete-time systems are causal or non cancausal, have memory or are memoryless, are linear or non linear, are time invariant or time varying. Justify your answer. In the following parts, x[n] is an arbitrary input..
Modify the display multiplexer/decoder design of Example 8.2 on page 323 to provide an 8-character alphanumeric scanned display, with eight 6-bit character code inputs. Use the ROM described in Exercise 8.11 to decode the character codes.
We will weigh objects by a strain gauge or R = 120 Ohms, GF= 2.02 mounted on copper column of 6-in. diameter. Find the change in resistance per pound placed on the column. Is this change an increase or decrease in resistance
Calculate the new mud developed by the coil and the peak flux and what is meant by mutual flux? by leakage flux?
What is the magnetic force on a square loop of current I placed in a uniformed magnetic field B with the plane of the loop perpendicular to the magnetic field. Explain
in the circuit shown in figure a-4 the zener diode is rated at 5.6 v and is operating in the zener region. if the
A stream can represent many different kinds of sources and destinations, including disk files, devices, other programs, and memory arrays. Discuss how to use the different data stream classes to move data to/from files.
How does the ripple content come into being in the conducting state region of the digital filter and how can it be avoided?
Design a circuit that will add either 1 or 2 to a 4-bit binary number N. Let the inputs N3, N2, N1, N0 represent N. The input K is a control signal. The circuit should have outputs M3, M2, M1, M0, which represent the 4-bit binary number M.
How would you orient a loop antenna in order to obtain maximum signal from an incident electromagnetic wave which has its magnetic field linearly polarized in the north-south direction?
