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..
