The audio frequency range of the bottlenose dolphin extends from approximately 250 Hz to 150 kHz. Frequencies between 250 Hz and ~ 50 kHz are thought to be used primarily in social communications, and "clicks" with frequencies above ~ 40 kHz are believed to be primarily used in echolocation.

Design an amplifier circuit that will selectively amplify dolphin social conversations. The microphone can be modeled as a sinusoidal voltage source with peak amplitude less than 15 mV in series with a 1 ohm resistor. The voltage delivered to the 1 kilo ohm resistor earphone should peak at approximately 1 V.
