Please write me a detailed answer in the following question. Thank you in advance.

A clipper circuit based on diodes are simple way to modify waveform in mechatronics. Assume that the two diodes shown in the circuit below are ideal diodes. If the input voltage in the circuit is a 1 kHz sinusoid with peak amplitude of 8V, sketch the Va.. (t) 10 kO 8V 10 kO Vin Vin(t) D2 Vout(t) RL Ims D1 6V -8V 4V Page | 1

LEDs (Light Emitting Diodes) conduct electricity in only one direction. A white LED tends tohave a voltage of 3.5, red 1.8 volts, blue 3.6 volts, and 2.1 volts for a green, orange or yellow LED.(a) You are to design a circuit comprising of 10 RED LEDs that can be powered up by a 12 Vbattery. Choose series/parallel combinations of LEDs and appropriate resistors. Note: You have to draw the complete circuit diagram showing the configuration includingbattery, all LEDs and resistors (with standard values only) and the power rating of eachresistor used. (b) Repeat part (a) if you have only BLUE lights in the circuit.(c) How will your design of part (a) change if you have different color LEDs (3 Red, 5 Blue,One Green and One Orange LED)?(d) Repeat part (c) if you have 230 V AC power instead of 12 V DC

Facts: Facts about Clampers A clamper is an electronic circuit that fixes either the positive or the negative peak excursions of a signal to a defined value by shifting its DC value. The clamper does not restrict the peak-to-peak excursion of the signal, it moves the whole signal up or down so as to place the peaks at the reference level. A diode clamp (a simple, common type) consists of a diode, which conducts electric current in only one direction and prevents the signal from exceeding the reference value; and a capacitor, which provides a DC offset from the stored charge. The capacitor forms a time constant with the resistor load, which determines the range of frequencies over which the clamper will be effective. Question: A clamping circuit has to have an independent source, a diode, a resistor, and a capacitor. To keep a constant voltage on the capacitor over the period of the input, the RC time constant must be large. A design rule of thumb is to make the RC time constant at…

a) Design a clamper circuit so that for the input waveform V,(t) as given in Figure 4(a), the output waveform V,(t) as shown in Figure 4(b) can be produced. You shall use ideal diode as part of your circuit design and provide the analysis of your design procedure with the aid of the simplified equivalent circuits.

For the last two parts, use the diagram to the right. d. V = -1.14V, R = 62, and the voltage across the diode is equal to 0.68V when it is "on". i V = e. V = -0.16V, R = 52, and the voltage across the diode is equal to 0.64V when it is "on". V= i = Vo ww R≤ KHI (Enter at least 3 significant digits. Each answer must be within 1% to be marked correct.) + ひ -

In the circuit below "I" is a DC current, and vs is a sinusoidal signal. Given the diode has VD= 0.75V at ID = 1.5mA, calculate both the AC and DC voltage across the diode (v.) when / = 1mA, R₁ 50092, and vs = 100cos(10ft). Assume the capacitors are very large. = +₁₁ R₂ w 15 ▷ |11
