Laboratorio de Electrónica I Laboratorio 2 Nombre del Estudiante: Fecha: Sección: Pre-laboratorio (1): 1) Demuestre los valores DC y RMS para una onda senoidal v(t) = V..cos(2 aft+). 2) Demuestre los valores DC y RMS para una onda senoidal (t) = K+V. CO2 +ft+ 3) Para la onda triangular mostrada en la Figura 2.2, calcule el valor DC y el valor RMS. personalise only Figura 2.2: Onda triangular con 0 offset 3) Se sabe que todo voltaje (o corriente) periódico de periodo T = 1/f puede expre- sarse por su serie de Fourier en la forma u(t) = V0 + V.cos(2n+ft+0) Para simplificar el ejercicio, tome solamente los tres primeros términos de la suma toria. Demuestre para esta onda, V? V? V3 Vpc = V y Vis= 12 +++ 4) Suponiendo que se tiene un voltímetro que no es de tipo RMS real. Tomando medidas con este voltimetro, usted encuentra los valores en DC, 3.5 Vpc y en AC encuentra 2.5 VAC ¿Cuál es el valor efectivo real de la onda? 5) Generalizando el problema anterior, ¿cómo encuentra el valor real efectivo de la onda usando un multímetro que no es de tipo RMS verdadero?

1) Show the DC and RMS values for a sine wave v (t) = Vm cos (2 πf t + φ). 2) Show the DC and RMS values for a sine wave v (t) = K + Vm cos (2 πf t + φ). 3) For the triangular wave shown in Figure 2.2, calculate the DC value and the value RMS. 3a) It is known that any periodic voltage (or current) of period T = 1 / f can express go for your Fourier series in the way ∞ v(t) = V0 +E)Vn cos(2 n π f t + φn) n=1 To simplify the exercise, take only the first three terms of the summation Show for this wave, VDC = V0 y VRMS = sqrt(V0^2+(V1^2/2)+(V2^2/2)+(V3^2/2)) 4) Assuming you have a voltmeter that is not of the real RMS type. Taking measured with this voltmeter, you find the valuesin DC, 3.5 VDC and in AC Find 2.5 VAC. What is the actual effective value of the wave? 5)Generalizing the above problem, how do you find the real effective value of the wave using a multimeter that is not true RMS type?
