not sure if this is just a simple plug and solve answer
A key design specification for this circuit is the allowable ripple In the output voltage waveform. This ripple is controlled by the size of the capacitor. If the ripple voltage is small then the relationship between this ripple value and the circuit component values is: VR where T is the period of the input signal (T = 1 / f). This equation gives a simple design rule that links the ripple voltage VR to the design variable C This equation is valid provided T RC, which will only be true if the ripple voltage is small relative to Vs. In a typical application this is exactly what we would want, so the assumption has to the valid if the circuit is to give an acceptable response. Find the ripple voltage if the sinewave amplitude is Vs = 5V, V = 0.7V, R = 10kOhm, f = 100kHz and C=22. OnF C = 4.7nFExplanation / Answer
Yes it is a simple plug in and solve question
T = 1/f = 1/100,000Hz = 0.00001s = 10-5s
(a) VR = (5V - 0.7V)T / (10^4)(2.2*10-8F) =
(b) VR = (5V - 0.7V)T / (10^4)(4.7*10-9F) =
