Description: The Electrocardiogram (ECG/EKG) is an electrical signal produced by the heart muscle. It has an amplitude of about 1mV, so a good amplifier is necessary. Electrical noise or electromagnetic interference (EMI), is generated by many common appliances, such as: power lines, lights, computers, cell phones, etc. When the ECG signal is amplified the noise is amplified as well and often swamps the ECG signal. Signal conditioning the ECG signal is necessary to acquire a good quiet ECG.

Description: The Electromyogram (EMG) is an electrical signal produced by skeletal muscle. It has an amplitude of about 1mV, so a good amplifier is necessary. Electrical noise or electromagnetic interference (EMI), is generated by many common appliances, such as: power lines, lights, computers, cell phones, etc. When the EMG signal is amplified the noise is amplified as well and often swamps the EMG signal.

Description: In this experiment we will look at the frequency response of various filters both analog as well as digital filters. The iWorx Recorder has the ability to output, through the Stimulator, a sine wave at a particular frequency. We will program Labscribe using Macros to change the frequency of the signal and measure the frequency response of the filter. We will look at how the order of a digital filter affects its frequency response.

Description: In this experiment we will look at various operational amplifier circuits. The IX-TA recorder has the ability to output, through the Stimulator, waveforms such as a sine wave or a square wave. We will use these signals as an input to various op-amp circuits and observe the output.

Description: Control an Arduino Claw, from your EMG or grip force.

Description: Make your Force Transducer, using a strain guage and an instrumentation amplifier. The main objective in this experiment is to correlate the change in voltage with the change in strain so that we can pinpoint a certain voltage change as indicative of a certain amount of force applied.
