3. If a charged capacitor \( C=35 \mu \mathrm{~F} \) is connected to a resistance \( R=120 \Omega \) as shown in the Figure, how much time will elapse until the voltage falls to \( 10 \% \) of its original (maximum) value? (Use \( \mathrm{v}=\mathrm{v}_{\mathrm{o}} \mathrm{e}^{\mathrm{H} / \mathrm{mc}} \) ) ( 20 pts ) (a) (b) You solved Given capacitor \( =C=35 \mu \mathrm{~F}=35 \times 10^{-6} \mathrm{~F} \) Resistance \( =\mathrm{R}=120 \Omega \) The maximum value of the voltage is, \[ \begin{aligned} & 35 \times 10^{-6} \mathrm{~F} \\ \mathrm{~V} & =\mathrm{V}_{0} e^{\frac{-t}{R C}} \\ \left(\frac{10}{100}\right) \mathrm{V}_{0} & =\mathrm{V}_{e} e^{-\frac{t}{R C}} \\ 0.1 & =e^{-\frac{t}{R C}} \\ \frac{-t}{R C} & =\ln (0.1) \\ & =-2.302 \end{aligned} \] The time is, \[ \begin{aligned} t & =2.302(R C) \\ & =2.302(120)\left(35 \times 10^{-6}\right) \\ & =9.67 \times 10^{-3} \mathrm{~s} \\ & =9.67 \mathrm{~ms} \end{aligned} \]

a> Design a Mealy-type pattern recognizer that can recognize 1010. The circuit has one input x where it receives one bit in every cycle, and one output y which should be 1 only when 1010 has been recognized (in other words, in the last 4 cycles, the circuit has received 1, 0, 1, 0 in that order). The circuit should be initialized to the proper state when the asynchronous input init=1. Design this circuit by using D flip-flops and any gates you'd like. b> What is the maximum frequency that your design can work? For this, assume that the gate delay of any logic gate = number of gate inputs * 0.1ns. Show your work.
