(1) € R₂ C₁ DIS TRI THR VCC C₂ 100 nF RST 555 Timer Figure 4(b) OUT CV GND V cc V out 12 V The desired oscillation frequency and duty cycle of the output signal Vout is 1200Hz and 88%, respectively, determine the design values of R₁ and C₁. State an assumption for resistor, R₂. Based on quantitative illustration, explain how to reduce the oscillation frequency by half and reduce the duty cycle by a factor of 1.5. State an assumption made for R₂. Show all the working steps.
