Considering x[n]=1+sin((3*pi*n)/8 + pi/4) + cos ((9*pi*n/24) + pi/4) , please design a filter that will pass the sine-wave portion, but ignore everything else. What is the filter's input response h(t)? In a real filter, what would you have to do differently? Thanks.
Please work through attached problem and let me know how you did it. Thank you.
Describe the operation and the characteristic of the general-purpose 741 op-amp provided in the attached file. i) Derive and calculate overall gain. ii) Determine the unity-gain bandwidth iii) Compare between BJT (741) op-amp and BiCMOS (CA3140) op-amp.
Please redraw the equivalent ladder logic diagram used to implement the hardwired circuit drawn in figure 5-48 (see attachment), wired using: a. A limit switch with a single NO contact connected to the PLC input module. b. A limit switch with a single NC contact connected to the PLC input module. Assuming the hardwired cir
Redraw each of the following programs corrected for the problem indicated (see attachment): a. Problem: nested programmed contact (Fig.5-44). b. Problem: vertical programmed contact (Fig.5-45). c. Problem: some logic ignored (Fig.5-46). d. Problem: too many series contacts(only 4 allowed) (Fig.5-47).
1. A user message is split into 15 frames, each of which has an 80% chance of arriving error-free. If no error control is used by the data link layer, how many times must the message be sent on the average to get the entire message through? 2. A communication channel has a bit rate of 14 kbps and an one-way propagation delay
Please work the problem and explain how you found the necessary values. Thank you. Design a differential amplifier as shown in Figure 11.28 incorporating a basic two transistor current source to establish Iq. The bias voltages are V+=15V and V-=-15V, the transistor parameters are Beta=180 and Va=100V, and the maximum forwar

These are practice tests and I really need to learn how to do them. Could you please help me understand and solve the entire problem? Any part of the bottom of any graph cutoff is merely a horizontal line showing ground w/ nothing else. See the attached file.
Hi, I know you do not do homework assignments but I am studying for a test tomorrow and these are practice tests w/ no answers and so I really need to learn how to do them. Could you please help me understand and SOLVE the entire problem (again, this is not a homework problem, just practice.)?

A unit for a telecommunications system is to be designed so as to have a minimum availability of 0.9994. The MTTR (mean time to repair) for the unit is estimated to be 24 hours. The unit is to consist of (n) effectively identical elements in parallel, from a reliability point of view. If the hazard rate of each of the elements i

Consider a tank with a cross-sectional area (see attachment for the rest of the question).
The attached graphs show simulated compression vs time for a spring-mass-dashpot system described by P(s) = 1/[s^2 + (B/m)s + k/m]. Parameters B, m, and k were each varied in turn with the other two held constant. Identify which parameter was varied in each graph, and whether it was increased or decreased from curve (a) to (d) i
An operational amplifier (Op-Amp) circuit is built to measure the temperature of an exothermic process in a lab. The circuit uses a thermistor (Resistance Temperature Detector) to monitor the target temperature and a voltmeter to measure the output voltage of the Op-Amp ciruit. Since the thermistor is a passive device, it requ
Why can discrete-time FIR digital filters be made exactly linear phase, whereas IIR digital filters cannot? I only require a sentence describing why - not any derivations of formulas etc!!!. I know what makes a filter exactly linear phase (impulse response must be symmetrical), but i don't know why IIR filters cannot be m
I was wondering if you can please help me with the solution to the following questions. 1a.
