You have an application that requires an output pulse of 60 seconds. Using a 1000 \mu F capacitor, calculate a resistor value that will meet the circuit requirements.

You are designing a power supply for a 100 W high-quality audio amplifier that will drive an 8 Ohm speaker.  The datasheet says you need approximately a 75 V Vcc rail to properly supply the transistor power stage.  To get the excellent performance you expect, you aim for 1% ripple, and choose a design that minimizes the amount of capacitance required to reduce cost.  Assume the diode drop is 0.7 V, and the input AC voltage available from a transformer is 75 sin(377t) V. a)How much capacitance do you need (a real-world value in μF) ? b)What is the ripple voltage at 10 W output power? c)What should be the minimum voltage rating of the capacitor(s)?

Using LTSpice, simulate the circuit below, use 2N3904 for the transistor. Part ! DC simulation: Measure VCE and Ic. Use .op for the simulation cmd. Remove all capacitors and input signals first. Part 2 AC simulation: Connect all capacitors now and apply an AC signal at the input with an amplitufe of 1mV and a frequency of 1kHz. Determine the Voltage gain of the circuit by dividing Vo with Vin. Show the output for both the DC and AC analysis. Take a screenshot of the circuit and the output voltages and waveforms.
