Can I use low-pass filter and resonant filter to create parallel filter bank model of cochlea?
I got a graph shows how the parallel filter bank should look like but I am not sure if I can use low-pass filter and resonant filter to be the filter 1.

Create a low pass filter (20dB/decade falloff) for an audio signal. Use the bode form type l design method (g-o./(s+ω.)). Use the bilinear transform to create the z-transform of the filter 4. Express the transform in the standard form ready for implementation in Simulink le the ratio of polynomials in z". There are no values given for W, or T so leave your expression in terms of these values.

23.1?
23.1 Active low-pass filter You can make a low-pass filter by putting a capacitor Cr and resistor Rf in parallel for Zj as shown in Figure 23.1. At low frequencies (well below the corner frequency), the feedback impedance is approximately Rf and the gain of a non-inverting amplifier is is 1 +R//R,. At high frequencies (well above the corner frequency),the impedance is approx- imately 1/(jwCs), and the gain of a non-inverting amplifier is...

Learning Goal: To analyze and design a passive, first-order low- pass filter using a series RL circuit. The analysis and design will be repeated for a series RC circuit. An electrocardiogram needs to detect periodic signals of approximately 1 Hz (since the resting heart rate of a healthy adult is between 55 and 70 beats per minute). The instrument operates in an electrical environment that is very noisy with a frequency of 60 Hz. It is desirable to have a...

b) When designing a FIR filters, the impulse response of the ideal low-pass filter is usually modified by multiplying it by a windowing function such as the Hamming window which is defined, for an odd number N of samples, by: (2n)-(N-I)-ns(N-1) N-12 wlnl 0.54 + 0.46 cos i What are the advantages of windowing with this function compared 2 with a standard rectangular window? ii) Design a 10th Order Hamming windowed FIR low-pass filter with cut- off frequency at 1000...

Part II: Low Pass Filter contd. Noise Removal To observe the noise removal capabilities of a low -pass filter, we will add a second input to the system to simulate noise Step 1: Alter your Simulink model by adding another sine wave function and use a Sum block to add the inputs together as the new input to the system. The second sine function...
