Can you upload a schematic of ne5532 audio amplifier circuit with a gain of one? And explain your circuit

3. An electrical fan is used to cool electrical components when the temperature exceeds a certain limit. The fan is controlled by a microcontroller that sends a logical-1 (3.3V) to an interface circuit that in turn activates the motor. When the temperature falls below the upper limit, the microcontroller sends a logical-0 (0.0V) to the interface circuit and the motor turns off. You are to design a simple transistor switch controller circuit for this application and decide to use the design shown Fan motor draws V2 24W when running "GND -24V D2 IN40010P u2 "DO" as NPN Transistor Ib below. You have the following npn transistors available to you: 2N2222A, SS8050, and 2N3904. a. If the fan draws 24W when running, what is the collector current, Ic? b. What would the maximum Vce voltage be across the transistor when the it is in cut-off? c. Based on the design criteria and the manufacturer's specifications for the 3 transistors, which one would work for this application? Why? d. For the…

2. Draw a labelled block diagram of a unity-gain multirate signal processing system that converts an input signal with sampling frequency 10 kHz to an output signal with sampling frequency 10.5 kHz.
