Question

Una taza de café se calienta hasta alcanzar una temperatura de 80 0C. Enseguida se expone al medio ambiente que se encuentra a una temperatura de 20 0C. Sabemos que la rapidez con la que cambia la temperatura del cuerpo se modela con la ecuación

dT =-.056(T-20) T(0)=80 dt

donde T(t) es la temperatura del cuerpo en el tiempo t y t se mide en minutos.

a) Determina la temperatura de la taza de café a los 10 minutos. b) ¿Cuál es la temperatura de la taza de café a largo plazo?

A clipper is a device that removes either the positive half (top half) or negative half (bottom half), or both positive and negative halves of the input AC signal. In other words, a clipper is a device that limits the positive amplitude or negative amplitude or both positive and negative amplitudes of the input AC signal. In some cases, a clipper removes a small portion of the positive half cycle or negative half cycle or both positive and negative half cycles. In the below circuit diagram, the positive half cycles are removed by using the series positive clipper. QUESTION: In your own opinion. Why do we need to clip a certain amount of voltage in positive or negative or on both sides? What is the benefit of that in our devices or circuits in doing such thing?
