Question

With the function generator set the corner frequency and the 150 ohm speaker in the circuit, could you hear anything? Why or why not, what happened to the volume as you increased the frequency? Why did this happen? How would this affect your design of an amplifier and the capacitors used? • (think about bandwidth and the application of your amplifier)

Explanation / Answer

When you set the corner frequency at 455.6 KHz, you can hear tha sound signal.

This will happen because of the frequency 455.6 KHz is the intermeidate frequency so that you will receive the audio signal

When the frequency is increased the signal gets distortion you will not hear the sound signal. the volume is muted.

This will affect the amplifier which we have design cannot fetch the signal. if you increasing the frequency further the capacitors cannot withstand.
