1. Recall the following setup from HW4: you are setting up a pair of PA speakers on a field in preparation for an outdoor event. Each speaker is 0.65 m wide, and the speakers have a center-to-center separation of 8.2 m. To test the speakers your coworker plays a single tone through the speakers whose frequency is 440 Hz. You are standing 52 m directly in front of the speakers and facing them. (a) Would you expect there to be any diffraction minima in this setup? If so, where? If not, why not? (b) Suppose we wish to create a directed beam of sound waves with that same frequency, 440 Hz. If we want the total width of this directed beam to increase by at most 5 m for every 100 m the beam goes forward, what is the smallest speaker we could use for this purpose?

You are given an audio amplifier. The input to the amplifier is a time varying voltage and the output of the amplifier is also a time varying voltage. Outline a practical procedure that can be used to determine the continuous time frequency response of the amplifier for frequencies ranging from -20kHz to 20kHz. You need to mention the equipment that you will use while working in a standard laboratory and how you will use it.

5. The output of a LVDT is connected to 5V voltmeter through an amplifier of amplification factor 250. The voltmeter scale has 100 divisions and the scale can be read to 1/5th of a division. An output of 2mV appears across the terminals of the LVDT when the core is displaced through a distance of 0.5mm. Calculate (a) the sensitivity of the LVDT, (b) that of the whole setup and (c) the resolution of the instrument in mm.
