The signal vin (t)=14cos(2 x 1000 t) mV is applied to an audio amplifier that has a negative voltage gain. The output signal is clipped when the amplitude of the sinusoidal waveform applied to the input port is greater than 100 mV. The amplifier is powered by a dual +/- 16 V power supply. Find the signal power of the amplified signal in W. Round your answer to two decimal places. 1) A sinusoidal test signal having an amplitude of 30 mV is applied to the input port of an amplifier with a perfectly linear transfer characteristic. The amplifier has a voltage gain Av= 146. Assume that the input signal is small enough to avoid any clipping of the output signal. Find the peak-to-peak value of the output signal in volts. Round your answer to two decimal places. 10) An amplifier that has a voltage gain of 125 is powered by a dual +/- 14 V power supply. A 4-ohm speaker is connected to the output port. Determine the RMS value of the largest input signal (sinusoid) in mV that the amplifier can process without clipping distortion. Round your answer to two decimal places. 12) The signal v in (t)=23cos(2 x 1000 t)+19cos(2 x 1500 t) mV is applied to the input port of an amplifier. Determine the total signal power of the output signal in W. given that the voltage gain of the amplifier is 132. Round your answer to two decimal places. Assume there is no clipping of the output signal. 13) An audio amplifier has input and output resistances of 125 kOhm and 19.3 Ohm respectively. The amplifier has a voltage gain of 90 and its output port is connected to a 17 ohm speaker. Assume the signal source is a CD player with a 75 ohm source resistor. Determine the power output of the amplifier in watts when the power of the music signal generated by the CD player is 143 mW.
