d) Design (Find the values of the R₁, R2, and C₁) an astable multivibrator circuit to have an output waveform as shown below in the figure (tH = 375µs and t₁ = 125µs). (Assume C₁ = C₂ and R₁ # R₂) and determine the frequency of oscillation and the duty cycle. R1: R2 C1 Q Vcc 4 555 5 C2 10nF I 8 1 3L -OVO tH = 375.0us tL = 125.0us

Can y help me fast

4- Design a boost converter that will have an output of 60 V from a 24-V source. Design for continuous inductor current and an output ripple voltage of less than one percent. The load is a resistance of 50 2. Assume ideal components for this design. VL ooooo ip - ^

RMS VALUE OF CURRENT LOAD( NEED NEAT HANDWRITTEN SOLUTION ONLY OTHERWISE DOWNVOTE).

Please try to understand the solution and try to answer in typing format please ASAP for the Pl

I need a clear step by step answer please and explanation please on how to obtain the values of Th and Tl and Vl

Can you answer the question step by step with clear writing ?

Q5/ Design a Colpitts oscillator as shown in figure below with 10 MHz output frequency. Find the values of C1, C2 and L1, then plot the waveforms at points P1 and P2. +Vcc R1 R4 P2 Cout Q1 Cin P1 R2 Re * Ce 升C1 * C2 Colpitts oscillator www.circuitstoday.com Your answer Q6/ Design a delay circuit using the IC 555, such that the delay between input and output to be 2 minutes. Draw the input/output waveforms. العربية الإنجليزية
