QUESTION Barry the Biologist has asked for your help to build an amplifier and filter to take small signals from his bird sensing microphones and amplify them so that he can capture the signals on his PC. The microphone produces AC signals at varying frequencies with 10 mV magnitude. His PC requires the signals to be 1 V magnitude. The signals that Bary is interested in are above 1 kHz Hz. He would like the filter to attenuate signals at...
A Biologist needs your help to build an amplifier and filter to take small signals from his bird sensing microphones and amplify them so that he can capture the signals on his PC. The microphone produces AC signals at varying frequencies with 10 mV magnitude. His PC requires the signals to be 1 V magnitude. The signals that Barry is interested in are above 1 kHz Hz. He would like the filter to attenuate signals at frequencies below 1 kHz....
Part A: Design the power supply component of your amplifier and filter. You will need to produce a dual-sided power supply with +10V, 0V and –10V using the 12 VAC plugpack as an AC source. Assume that your amplifier and filter will draw around 10 mA of current on both the positive and negative voltage supplies. Your design should include components to minimise voltage ripple. Show calculations for the selection of components where practical. Show a circuit diagram for the...
QUESTION 1 Anna the Audiophile has asked for your help to build an amplifier and filter to take small signals from her hifi system and amplify them so that she can drive her new subwoofer. The hifi system produces AC signals at varying frequencies with 250mVrms maximum magnitude Her subwoofer requires the signals to be 20 Vrms maximum magnitude. The signals that Anna is interested in are below 200 Hz. She would like the filter to attenuate signals at frequencies...
ONLY NEED HELP WITH III and IV PLEASE (e) A second stage, shown in Figure 3, is cascaded directly after the output of the circuit in Figure 1 R4 Figure 3 (i) Show that the combined response of the complete circuit is given by: (4 marks) (ii) The two cascaded stages form a bandpass filter, which only amplifies a specific range of frequencies. This range of frequencies is known as the passband. Using the values chosen in (a) for Figure...

Yes, this is one problem. Please solve ALL PARTS. Guaranteed thumbs up for the person who solves it. 3 1. Photodiode amplifier circuit You are designinga CF photosensor circuit for a light detection and ranging LiDAR) system in autonomous vehicles. The circuit utilizes a transimpedance amplifier to convert low-level RF photodiode current signal to a usable voltage output. It consists of a photodiode, an amplifier, and feedback capacitor/resistor pair as shown in Figure 1. We will derive simple equations to...
