Components Required for the Lab: These are your design constraints for this Lab: You are required to use the LM318 Operational Amplifier, and the 0.22uF capacitor as one of the two frequency determining components. All other resistor & capacitor values are determined by your design calculations, but you may only use standard value components in the EECS Shop. Standard Values will be discussed in the lab. Circuit Diagram: Your circuit configuration looks something like this: Low Pass Date Last Modified: 5/6/2013 11:53 PM 2
HIGH PASS Note that the op-amp is used in its non-inverting mode (the input is connected to pin 3). The resistor-capacitor configuration between the input and the op-amp's non-inverting input provides the desired filtering. Procedure: Week 1: 1. <strong>Design</strong> a <strong>Filter</strong> for the given Cut-off Frequency and Gain. The Relevant Equations for both Low pass & High pass circuits are: Gain: = 1 + R F / R G Cut off Frequency = 1 / (2 π RC) Note: Use C = 0.22uF for the capacitor in the filter network. Select R F and R G between 1 [k] and 50 [k]. If R F and R G are less than 100 [] (chosen to be 1 [k] or greater for a safety margin) too much current will flow through the feedback loop, and the LM 318 will be damaged. If R F and R G are greater than 50 [k] not enough current will flow through the feedback loop, and will invalidate some of the other practical assumptions of the LM 318.
