Q4: A Low pass filter (current mode conversion) is shown below: R: io Using a current source I, an R and L, to sketch a high pass filter and describe briefly how it works?

Need Help Asap What is an active low pass filter? Explain its impact and application in engineering problems.

This is signal and system question...please help me with this...thanks

Q6. Design a two-pole low-pass Butterworth filter for an audio amplifier application. The circuit is to be designed such that the bandwidth is 20   kHz.

Task Four: Hearing Aid Volume Control system The human ear reacts to various frequencies in a different way. The frequency range between 1 and 3 kHz is the most sensitive frequencies, and the average sound level is 60 dB. Design a Hearing Aid Volume Control system that receives a signal from a microphone then amplify and passe the most sensitive frequencies only. Consider the following specifications in your active filter design: a. Use Op-amp in your design. b. Use a 15-volt battery. c. The passband volage gain is more than 10 dB. Design procedure: 1. Draw the schematic diagram for the circuit to be analyzed. 2. Mathematically analyze the circuit and predict the behavior of the circuit under a variety of conditions. 3. Build this circuit on a breadboard or other convenient medium. Carefully measure all voltages and currents, to verify the accuracy of your analysis. 4. Verify the design by simulating the circuit. Carefully measure all voltages and currents, to verify the accuracy of…

Q4 Design an active highpass filter with a gain of 10, a corner frequency of 2 kHz, and a gain roll-off rate of 40 dB/decade.

(b) High-frequency ECG biopotentials analysis in the ST-T segment of a high-resolution ECG signal recording requires the analysis of signal components above 30 Ilz and below 800 Hz. Design a first order band pass passive filter to accommodate this specified frequency bandwidth. Sketch the circuit configuration. You may use an op- amp buffer stage in your circuit design.
