pleease have step by step solution for each part and explain. also i dont understand what to do with -3Db cutoff frequency.

3. An essential part of an AC-DC power supply circuit is the filter, used to separate the residual AC (called the "ripple" voltage) from the DC voltage prior to output. Here are two simple AC-DC power supply circuits, one without a filter and one with: Plug unfiltered Plug Filter Vatered Draw the respective output voltage waveforms of these two power supply circuits (unfiltered versus filtered). Explain why that type of filter circuit is needed.

At two distinct places, a signal is measured. At the first point, the power is P1, and at the second point, it is P2. The decibel level is zero. This denotes

Can this circuit be solved using supernodes analysis ?

A very common problem in instrumentation is that of interference of the telemetry that is to be measured. One of the primary sources of the interference is the power line. This is particularly true for high impedance circuits. Another path for this noise is ground-loops. One possible solution is to use a notch filter to remove the 50HZ component. Design a suitable notch filter for this purpose.

please answer question 1.b quickly… please answer base on my matric number not as same like question.. my matric no is 201061325 so the last 3 digit is 325 so the selected low cut-off frequency is equal to the 32 khz while the high cut-off frequency is 5khz … so use the value that i give... thank you

explain how to find the resonance frequency, 3dB lower limit frequency, upper limit frequency, bandwidth BW, and Q values ​​in the above parallel resonance circuit.     However, since there is an internal resistance of 51 ohms in the function generator, please take this into consideration.

Signal and system problem.plz solve every step with formula

What is the use of phase cross over frequency? How will you find it?

To subtract (M – N) in base r, we add (M + r’s complement of N). Result = M + (rn – N). If M > N, then result is [M – N + rn], and (rn is an end carry and should not be neglected).  True  False

The frequency deviation is the amount of change in carrier frequency produced by the modulating signal. Select one: O True O False

(v). Determine the poles and zeros of the designed closed loop transfer function and show their positions on s-plane.

Construct a signal flow graph from the following equations. Obtain overall TF using Mason's gain formula. Where x_{1} is i/p variable & x_{5} is a/p variable. x_{2} = a_{12}*x_{1} + a_{32}*x_{3} + a_{42}*x_{4} + a_{52}*x_{5} x_{5} = a_{35}*x_{3} + a_{45}*x_{4} x_{4} = a_{34}*x_{3} + a_{44}*x_{4} x_{3} = a_{23}*x_{2}
