What is the settling time for your output signal (BRF_OUT)? For this question, We define the settling time as the period of time it has taken for the output to settle into a steady state - ie when your oscillation first decays (aka reduces) to less than approximately 1/20 (5%) of the initial value. (a) Settling time = 22 μs Your last answer was interpreted as follows: Incorrect answer. Check 22 222 What is the peak to peak output voltage (BRF_OUT pp) at the steady state condition? You may need to use the zoom function to perform this calculation. Select a time point that is two times the settling time you answered in the question above. Answer to within 10% accuracy. (a) BRF_OUT pp= mVpp As you may have noticed, the output voltage amplitude is a tiny fraction of the input voltage, i.e. it has been significantly attenuated. Calculate the attenuation (decibels = dB) in the output signal as compared to the input based on the formula given below. Answer to within 1% accuracy. Attenuation(dB) = 20log10(- BRF_OUTP PP V inpp Hint: Attenuation is almost always presented as a negative number, as it shows a reduction in power relative to the starting point (compare with Gain, which we will cover later in the semester).

LTspice implementation of Band Reject Filter The source shown in Figure 5 should be an input sine wave signal (Vin) with an amplitude of 0.5V (1V pp) and a frequency 100 kHz. This is to emulate the interference part of the waveform you observed in Figure 3. Set your DC offset to zero volts. Perform a transient analysis as shown. Plot the input node Vin and the output node BRF_OUT.
