Discrete Filter Notes (PDF 36p)
The objective of this section will be to show how to use the first- and second-order filters to achieve higher order filters. We shall also introduce a general, second-order stage called the biquad.

The other approach uses a ladder configuration and is presented in this section. Both approaches are used to design successful higher-order active filters. The cascade approach is easier to design and tune but does not have the insensitivity to component variation found in the ladder approach.
Fundamental IC Noise paper (PDF)
Most people find the subject of noise mysterious, and there is, under- standably, much confusion about it. Although the fundamental physical concepts behind noise are simple. much of this simplicity is often obscured by the mathematics invoked to compute expressions for the noise.

Initially both semiconductors are totally neutral. The concentration of positive and negative carriers are quite different on opposite sides of the junction and the thermal energy-powered diffusion of positive carriers into the N-type material and negative carriers into the P-type material occurs. The N-type material acquires an excess of positive charge near the junction and the P-type material acquires an excess of negative charge.

Procedures for Output Filtering Lab
In this lab, you complete the quarter project. First, you verify that the entire project can be powered from a 10 V supply rail (provided by two different LM317 type regulators). Next, you build and test the filter that smooths the demodulated signal. Penultimately, you build and test the high current output stage that drives an 8 Ω speaker. Finally, you integrate all components together. In this document, we present some basic topics and procedures to help you complete (and understand) the lab.
