HW 10 Assigned 26 April 2004, due 3 May 2004 Read: Ch. 6 “Salarybels” Really about the logarithmic measures – called decibels – that are used to quantify voltages and currents Sec. 28.4 – Operational amplifiers Ch. 31 Communication Systems This topic will be discussed in class Problem 6.1 Use of the reference power when giving powers in decibels Problem 6.3 Voltage gain of an amplifier in decibels. (Note: the power rating of a loudspeaker indicates the electrical power delivered to the speaker, not the acoustical power that it produces.) Problem 28.10 Ideal op-amp problem Problem 28.12 Ideal op-amp problem Problem 5. Derive the expression for the output voltage of the differentiator (ideal) opamp circuit shown in the op-amp notes handed out in class on Monday April 26..
