Instructor: C. Davila
1. For the monostable multivibrator described in lecture 15, derive
the formula for the pulse width:

2. for the astable multivibrator described in lecture 16, derive the formula for the half-period of the multivibrator output:

3. Show that the solution to the wave equation:

is valid provided that the dispersion equation is satisfied:

4. Show how the ultrasound Doppler flowmeter hardware can be modified to provide two pulses per va cycle rather than one pulse per cycle.
5. For a laminar flow scenario, sketch a reasonable depiction of va and describe its relationship to the demultiplexer output on slide 488.
