    D/A Communications - Minimum bandwidth of a channel

    Homework Statement Homework Equations The given channel transfer function and PSDs. Note that the capital Pi symbol in the PSD of the message symbolizes the rectangle function so Sm(f) = 8rect(f/8000) The Attempt at a Solution From my understanding, channel noise is not filtered at this...

    Engineering PSPICE - simulation of CMOS astable circuit

    The output plots? Alright. I'm assuming you mean the capacitor voltage when you say Vcc. V(1) is VDD = 5 V, V(2) is Vi and Vcc (same node), V(3) is the output of the first inverter, V(4) is the output of the second inverter.

    Engineering Circuit Analysis of a Positive Offset Clamping Diode Circuit

    Not exactly a triangle wave, but it still follows the same general shape. Top/pink is Vo, middle/purple is Vs, bottom/red is Vc.

    Engineering Circuit Analysis of a Positive Offset Clamping Diode Circuit

    Yes, I simulated the circuit using PSPICE. Just from observation of the circuit, I can tell how it behaves for the first few cycles, even without the simulation. I just can't manage to write it down with some work. At 0 seconds, is the circuit assumed to be in DC steady state? Is it valid...

    Engineering Circuit Analysis of a Positive Offset Clamping Diode Circuit

    Homework Statement Plot the waveforms for capacitor voltage VC, output voltage Vo, and diode voltage Vd given that Vs is a 20 Vpp triangle wave with period T. Use CVD model with diode VON = 0.7 V. Homework Equations KVLs? The Attempt at a Solution From my basic...

    Qualitative Understanding of MOSFET in Depletion

    Homework Statement No actual problem statement. I'm just having trouble understanding what is happening during the depletion and inversion stages. See the attached picture. During the depletion stage, what does it mean by "immobile acceptor ions?" Homework Equations None The...
