A circuit that combines two or more signals is called a mixer. In this lab, your goal is to build a mixer that combines the signals generated by two voltage sources, V1 and V2, where:
V1 is a 1 kHz square wave that varies between 0V and +1V, and
V2 is a 5 kHz sine wave that varies between 1V and +1V.
Please design a circuit that mixes V1 and V2 to produce Vout such that
Vout≈12V1+16V2.
The resulting output should be similar to that shown in Figure 1. The maximum value of the output is approximately 667mV and the minimum value is approximately −167mV.
Enter your circuit below, using the appropriate configuration of resistors. Please do not modify the wiring or parameters of the voltage sources  your goal is to take the signals they generate and combine them, not to change what is generated. Run a 5ms transient analysis to verify the correct operation of your circuit. We will be checking for the transient waveform at the "output" node.

The min value of 12V1 is 0
the min value of 16V2 is less than 16*1.4
so the min value of 12V1+16V2 is about 16*1.4
So I am wondering exactly about this statement: Vout≈12V1+16V2.
The resulting output should be similar to that shown in Figure 1. The maximum value of the output is approximately 667mV and the minimum value is approximately −167mV. 
Consider a deuteron in a cyclotron with field strength 0.5T. The deuteron is accelerated twice per rotation by a potential of V=25 kV. (a) If the radius of the cyclotron is 2 meter, what is the maximum energy of the deuteron? Express your answer in Joules (the deuteron mass is 3.34×10−27kg) b)Starting from a negligibly small velocity, how many full rotations does the deuteron need before it reaches this maximum energy? c) What is the time it takes for the deuteron to make one complete rotation when its energy is about 500 keV and when it is about 5 MeV? Ignore possible relativistic effect
I have b) 500
Anyone for a) and c)?
