Con la ayuda de un multímetro digital o analógico podemos visualizar la frecuencia de determinado circuito, tal como se hace con el capacímetro. Se pueden medir frecuencias hasta 200 KHz. La frecuencia que se mide es amplificada por Q1, pero la señal de entrada estó limitada a un máximo de alrededor de 2 voltios de pico a pico por R1, D1 y D2... Publicado
