Please submit solutions to the following problems on
**Monday, March 30**.

- 1.
- A circuit and its phasor/impedance equivalent are
shown below.
Determine the current
*i*(*t*), and sketch*i*(*t*) versus*t*. Indicate the sine wave amplitude, frequency, and phase in the sketch. Note that .**CIRCUIT OMITTED IN HTML DOCUMENT -- SEE PAPER COPY** - 2.
- Classify each circuit below as one of the following types
of filter: low-pass, high-pass, or band-pass.
You can do this either by thinking about how each circuit operates
as and ,or you can analyze the circuits as voltage dividers with
impedances and study the resulting equations.
