You have been tasked by your employer to design a circuit that will process a raw EEG signal into its various components (alpha, beta, theta, and delta waves) as part of a brain-machine interface (BMI) device. This BMI device requires that each output waveform has a voltage of at least 2V in order to be properly processed by downstream hardware. In one of your EEG experiments, you obtained the voltage measurement displayed in Figure 2. The raw data has been recorded to an arbitrary voltage source on your function generator. Figure 2. Measured EEG signal Your objective is to take the EEG input signal and: a) Separate out the beta, alpha, theta, and delta waveforms b) Estimate the Vpp of each individual waveform before amplification c) Provide a gain to each individual waveform such that each output has a final Vpp of 2V d) Assess the frequency of each individual waveform This will be achieved through the design, construction, and assessment of an electric circuit. Your employer has allocated you a budget of $11.00 to spend on components for your final design. A single resistor costs $0.20 A single capacitor costs $0.35 A single operational amplifier
