In Multisim (or any other circuit drawing software) design a monitoring system to detect proximity of an object, using a Reed switch and transistors.  An LED or a light can be used as an indicator; when two objects are in close proximity of each other an LED will lit. Then design should use a relay to switch on a siren.  Use a 12 VDC relay (included in your component bag) with sufficient power rating for the contacts to turn on the siren. When the input voltage of the relay is close to 12V, the siren will sound and if the relay input is close to 0V the siren will go off. For the low sound volume, design an amplifier to amplify the output of the siren by a factor of 10. Assume that you can remove the speaker of the siren and place a transistor/Opamp amplifier between the siren circuit output and the 8Ω/2Wspeaker. Design the amplifier and specify your valid assumptions.

INSTRUCTIONS:  Under DC conditions, in steady state, find the current i and the voltage Vo.   the exercise of the image, it is in Spanish but it is easy to understand. Note:Please describe what method/application you are using in each step. (so I can understand it) (and that the result is good, of course).

Hi im struggling to understand how you would sketch DC component Va and AC component va for the following questions. Could you show me how on both questions so i understand how to do it on different scenarios. thank you.Also is there like a universal formula i can use as every graph is not the same. Also can u show how to identify the period of each graph.

Please no hand writing solution

Use image below for question ! 

The statements given below in terms of linearity, time invariance and causality classify. Y1 (n) = 5x(n) + 2x²(n) y2(n) = x(n – 1) – 2x(n – 1)

EXAMPLE 6 For the circuit in Fig. 35: ( page 425) a.Find the mathematical expression for the transient behavior of yC, iC, and yR if the switch is closed at t_ 0 s. b. Plot the waveform of yC versus the time constant of the network. c. Plot the waveform of yC versus time. d. Plot the waveforms of iC and yR versus the time constant of the network. e. What is the value of yC at t _ 20 ms? f. On a practical basis, how much time must pass before we can assume that the charging phase has passed? g. When the charging phase has passed, how much charge is sitting on the plates? h. If the capacitor has a leakage resistance of 10,000 M_, what is the initial leakage current? Once the capacitor is separated from the circuit, how long will it take to totally discharge, assuming a linear (unchanging) discharge rate? 8 kfl E 40 V c4 µF vC FIG. 35 Transient network for Example 6.

1.Utilize an appropriate R-C circuit powered by a 120 V DC source. This RC circuit will be the energy source to power a single Neon Lamp. 2. Neon and other gas-based lamps often require a threshold voltage before they turn "on", i.e. emit light. The neon lamp you will use has a turn-on voltage of 70 V. In the provided LTspice model of such a neon lamp, you can explore how this light turns on and off (i.e. the current through the lamp is high when the lamp is on), when it is powered by a pulsed voltage source. Play around with the pulsed source parameters to investigate the lamp's behavior. However, keep the lamps LIspice parameters fixed (i.e. do not change the attributes of the lamp). 3. Using the RC circuit Power your Neon Lamp so that it turns on every 0.1 seconds (10 Hz frequency). The time for which it remains on is not critical, but should obviously be much less than 0.1 seconds.
