Design a “rumble” filter for audio. It should pass frequencies greater than 20 Hz. Assume the source impedance is zero (that is, the voltage supply is perfect) and 10K minimum load impedance (which means the load could be variable and have a much higher impedance). Make a figure showing the expected output of the filter designed.

new audio preamp suffers from 60 Hz hum from the powerline. Assuming that the desired audio frequencies are greater than 500 Hz, design a filter that goes between the audio source and the preamp (as shown in the picture). To keep things simple, design a filter using ONLY ONE resistor and one inductor. Determine appropriate values for these components such that the filter has 15 dB attenuation at 60Hz. show your work/thought process please. VAUDIO Audio Preamp Your Filter VAUDIO...
Problem 1 (25 Pts) Design a low pass multistage Butterworth filter that simultaneously meets the following design requirements: 1. Minimum attenuation of 24 dB at 1000 Hz and 2.

skipped part. Tutorial Exercise The RC high-pass filter shown in the figure below has a resistance R -0.500 n and a capacitance C = 673 pF. What is the ratio of the amplitude of the output voltage to that of the input voltage for this filter for a source frequency of 583 Hz? R Scout Step 1 The source frequency given in this problem is not an especially high audio frequency so we might guess that the voltage transfer ratio...

Problem 3: Design Problem On Figure P3a, you have a Common Source (CS) n-channel MOSFET amplifier. Notice the absence of a source resistor Rsig and load resistor R. If we know how the present amplifier (the one on Figure P3a) behaves without Rsig and RL, we can infer its behaviors if Rsig and R were to be added. design the amplifier circuit on Figure P3a, i.e., you have to find appropriate values for RGj You are to RG,, RD, and...
