- Amplificador operacional LM741
- Resistencias y capacitores para establecer las frecuencias de corte deseadas.
- Opcional: Resistencia y capacitor de retroalimentación para controlar la ganancia del amplificador operacional.
Diseño del circuito- Filtro pasa altas: Diseñaremos este filtro para cortar frecuencias por debajo de 80 Hz.
- Filtro pasa bajas: Diseñaremos este filtro para cortar frecuencias por encima de 180 Hz.
Cálculos de los componentes-
Filtro pasa altas:
- Frecuencia de corte ($f_c$) = 80 Hz
- La fórmula para la frecuencia de corte de un filtro RC pasa altas es:
fc=2πR1C11
- Selecciona un valor común para $C_1$, por ejemplo, $C_1 = 10 , \mu\text{F}$.
- Calcula $R_1$:
R1=2π×80×10×10−61≈198.9Ω
-
Filtro pasa bajas:
- Frecuencia de corte ($f_c$) = 180 Hz
- La fórmula para la frecuencia de corte de un filtro RC pasa bajas es:
fc=2πR2C21
- Selecciona un valor común para $C_2$, por ejemplo, $C_2 = 56 , \mu\text{F}$.
- Calcula $R_2$:
R2=2π×180×56×10−61≈15.9Ω
Conexiones del circuito-
Filtro pasa altas:
- Conecta la entrada de señal a la serie $R_1$, $C_1$ a tierra.
- La unión entre $R_1$ y $C_1$ se conecta al terminal de entrada no inversora del LM741.
-
Filtro pasa bajas:
- Conecta $R_2$ desde la salida del LM741 a la serie con $C_2$ a tierra.
- La unión entre $R_2$ y $C_2$ se conecta a la salida final del filtro.
