Problem 8.36 requires reference to 8.13, I only need 8.36
solved
For low frequency, i.e. when signal does not pass
then since at low frequencies
and thus when f goes to f/2, power goes as square of f = 1/4 of initial power

Problem 4: Design a first-order, strictly causal, low-pass DT filter to recover a low frequency sensor signal, corrupted by high frequency noise. The signal can contain frequencies up to 10HZ and the noise has frequencies above IkHz. The sampling frequency is 20kHz and you may assume that there is no aliasing. If the highest distortion allowed for the signal is 1% in amplitude, what is the worst-case attenuation of the noise signal? Problem 4: Design a first-order, strictly causal, low-pass...
Problem 3) (15 points) An RC filter is designed with a cutoff frequency of 100 Hz. If a low-pass first order filter is used, determine the attenuation (Attenuation %, and Attenuation(dB)) of the filtered analog signal at 50, 75 and 200 Hz. (use k -1) o Determine the order of the filter if magnitude ratio of <0.01 is needed at 200 Hz. Problem 3) (15 points) An RC filter is designed with a cutoff frequency of 100 Hz. If a...
QuestionThree useful circuit combinations in AC circuits are high-pass,"low-pass," and band-pass" filters. In the first case, high frequency signals are allow to through the filter while low frequencies are not while the opposite is true in the second case. The third case allows Jonly limited region of frequencies through the filter. Examine the series RLC circuit and iden tify what behaves in the circuit like the different filter combinations. 0.8 H 0000 Reactance XL (12) W 1.0 kN2 100 101...

What is the answer to question 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...

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...
Notes you have to use MathLab No Hand Writing and Write answer by typing PDF Or document word. Active 1st Order Filters Objective An active filter is a type of analog electronic filter distinguished by the use of one or more active components. Typically this will be a yacuum tube, or solid-state Active filters have three main advantages over passive filters: Inductors can be avoided. Passive filters without inductors cannot obtain a high Q (low damping), but with them are...
