Voltage supply 5 V. Input signal is an audiosignal 100 to 3000 Hz. This signal should be split in 8 frequency bands and a led should indicate if the the frequencys in this band contribute to the whole signal (compared to a treshold), in a 1/0 setting: the output should be one (led full on) when strenght of signal in band is over treshold, otherwise output should be 0. Use as few components as possible.

"1N4007 Flyback Diode" (Protection across the motor) Wiring Connections to map out: - Connect the 12V Power Supply Positive (+12V) to Pin 3 of the B10K Potentiometer and to the Positive terminal of the 12V DC Motor. - Connect the 12V Power Supply Negative (GND) to Pin 1 of the B10K Potentiometer and to the Source (S) pin of the UT100N03L MOSFET. - Connect Pin 2 (Wiper) of the B10K Potentiometer directly to the Gate (G) pin of the UT100N03L MOSFET. - Connect the Negative terminal of the 12V DC Motor to the Drain (D) pin of the UT100N03L MOSFET. - Place the 1N4007 Flyback Diode in parallel across the 12V DC Motor terminals, with the Cathode (striped side) connected to the motor's positive terminal and the Anode connected to the motor's negative terminal. Layout Orientation: Arrange left-to-right starting with the 12V Power Supply, moving to the Potentiometer, then the UT100N03L MOSFET, and placing the Motor at the top right.

A Voltage divider with 2 resistors
Create the small-signal hybrid-pi equivalent circuit for a common-emitter BJT amplifier. Assume: All DC voltage supplies (+5 V and -5 V) are replaced by AC ground. Coupling capacitor CCC_CCC is replaced by a short circuit. Bypass capacitor CEC_ECE is replaced by a short circuit. Early voltage VA=∞V_A = \inftyVA=∞, so omit ror_oro. Circuit layout: On the left is an AC voltage source labeled vsv_svs. The positive terminal of vsv_svs connects to a resistor RS=2.5 kΩR_S = 2.5\,k\OmegaRS=2.5kΩ. The other end of RSR_SRS connects to the transistor base node. Use the hybrid-pi transistor model: Place a resistor rπr_\pirπ between the base node and ground. The emitter is directly connected to AC ground. Place a dependent current source between collector and emitter. The current source value is gmvπg_m v_\pigmvπ. The arrow points from collector to emitter. vπv_\pivπ is the voltage across rπr_\pirπ, measured from base to emitter. Collector network: The collector node connects to resistor RCR_CRC. The other end of RCR_CRC is connected to AC ground. The collector node also connects to load resistor RL=5 kΩR_L = 5\,k\OmegaRL=5kΩ. The other end of RLR_LRL is connected to AC ground. Thus RCR_CRC and RLR_LRL are both connected between the collector node and ground, appearing in parallel. Output: Label the collector node as vov_ovo. Measure vov_ovo with respect to ground. Component labels: RS=2.5 kΩR_S = 2.5\,k\OmegaRS=2.5kΩ rπ=12 kΩr_\pi = 12\,k\Omegarπ=12kΩ RC≈10.8 kΩR_C \approx 10.8\,k\OmegaRC≈10.8kΩ RL=5 kΩR_L = 5\,k\OmegaRL=5kΩ Dependent current source =gmvπ= g_m v_\pi=gmvπ gm=0.01 Sg_m = 0.01\,Sgm=0.01S Draw the circuit as a standard small-signal BJT hybrid-pi model with ground at the emitter.
Draw a schematic diagram. A single 3V battery power source connects to a switch. After the switch, the wire splits into two parallel branches. The first branch has two light bulbs in series. The second branch has two light bulbs in series. These two branches merge back into a single path. This path connects to a fifth light bulb in series, which then connects back to the negative terminal of the 3V battery
Draw a schematic diagram. Two batteries are connected in series. The positive terminal connects to a switch. After the switch, the wire splits into two parallel branches. The first branch has two light bulbs connected in series. The second branch has two light bulbs connected in series. These two branches merge back together into a single path. This path connects to a fifth light bulb in series, which then connects back to the negative terminal of the battery bank
This diagram shows a combination series-parallel circuit powered by two batteries connected in series at the bottom right. The current flows from the positive terminal of the batteries through a single knife switch, after which the main wire splits into two parallel branches on the left. The top branch contains two light bulbs connected in series, and the middle branch similarly contains two light bulbs connected in series. The current coming out of both of these parallel pairs then merges back into a single wire before passing through a fifth individual light bulb on the right side, which finally completes the loop by connecting back to the negative terminal of the battery bank.

a electronic tube based audio amplifier with two triode stages with ECC88 and an audio output driver based on EL519 or equivalent, The audio output shall be made through audio transformer appropriate for a load of 8 ohm. Just want one single mono channel; I suggest using paper capacitors and 1/2 w resistors. The power supply is to be external but voltage levels for valves and heater bus shall be indicated in the schematics. The circuit must have RF supression capacitors or filters wherever needed. The pin numbers for each tube valve shall be cleared marked in the schematics.
