Current AnnouncementsThe Amplifier Circuit is here. 04/14/04 (modified 04/19/04): Assignments for this week:
04/07/04: Read the HIP4080A datasheet and application notes for Thursday.04/03/04: Looking for more things to do? Play with Allegro and become familiar with its capabilities. Also, there are now extension projects that you can do, on the Example Problems page.3/23/04: Build the simple PWM amplifier, with op-amps for triangle-wave generation and comparison, and an inductor and capacitor for "smoothing". Build these amplifiers on your circuit boards, using PSPICE as much as it helps you.3/02/04: Lab 4 is to model in PSPICE and build on your bread boards a pseudo-random white noise generator. Build a system as described in section 9.33 of The Art (either the 16-bit or 24-bit versions) and apply a lowpass filter to get analog noise. You may find sections around 9.33 useful as well. Play your white noise through a speaker in lab and describe any features of the sound. Try to show in PSPICE that the Fourier transform of your output shows an approximately even distribution of energy in audio frequencies (between 20 Hz and 20 kHz). Include in a lab report, emailed to jrising @ olin.edu, your PSPICE work and how it relates to the system you created on your breadboard. Do not take apart your circuits after you are done. Keep your breadboards. Parts will arive Wednesday, including 8-bit shift registers which can be cascaded to form larger registers. 2/24/04: Lab 3 is available. Due next Tuesday. We've switched over to Time-Based Grading! Read more on the policies page! 2/09/04: Lab 2 is out - this is also your homework for this week. It is due next Tuesday. 2/03/04:Please install the most recent version of Cadence PSpice, version 15.0, and remove any previous versions, by the end of the week. Instructions for installing Cadence PSpice are at http://www.olin.edu/it/docs/Installing_Cadence_PSpice_PSD_15.pdf. Note that the install is over 1 GB and will take a while. 1/29/04:There was no additional homework assigned for Tuesday, although redos of homework 2 are due then.
1/23/04: If you do not have Cadence / Pspice already on your laptop, you can install the student version of cadence / pspice from the software page at left.
