6.Determine the voltage across each diode assuming the practical model.
7.Determine the voltage across each diode assuming an ideal diode.
8.Determine the voltage across each diode using the complete diode model .
You need to add a short justification for your answer. Only mentioning (a), (b) .. does not receive any
credit.
2.
(c)
The zero-level detector is one application of a comparator. , the inverting input is grounded
producing a zero level.
The input signal voltage is applied to the noninverting input.
4.
(d)
The effects of noise can be reduced by using positive feedback and using hysteresis.
Essentially
called positive feedback, hysteresis is when the amplifier has a high reference level when the input
voltage travels from low to high more than going from high to low.
6.
(s)
In a comparator with hysteresis has two trigger points. , It states there are two reference levels
often referred to as the upper trigger point (UTP) and the lower trigger point (LTP).
They are established
with a positive feedback arrangement.
With the input connected to the resistive voltage divider where a
portion of the output will be fed back to the input.
8. (b) A summing amplifier can have any number of inputs.

10.
(a)
An average amplifier has five inputs. The ratio
must be 0.2.
This is accomplished by setting
the ratio equal to the reciprocal of the number of inputs.
12.
(b)
In an ideal integrator, the feedback element is a capacitor. , the capacitor forms an RC circuit with
the input resistor. The capacitor is charged with the proportionality of the charging current
and the
time
(t)
