In a non-inverting comparator, the input signal is applied to the (a)   terminal of the op-amp.

Noise near the threshold voltage (Vref) can cause the comparator output to rapidly switch, a problem known as output (a)   .

Hysteresis creates two threshold voltages called the upper trigger point (VUTP) and the lower trigger point (VLTP). This is achieved by adding (a)   feedback.

A comparator with built-in hysteresis is commonly known as a (a)   trigger.

Output bounding uses (a)   diodes to limit the output voltage to a safe level.

A summing amplifier typically uses an op-amp in the (a)   configuration.

In a unity-gain summing amplifier, the output is equal to the (a)   of the input voltages, multiplied by –1.

A non-inverting comparator uses a voltage divider to create a reference voltage.
If R1 = 22 kΩ and R2 = 3.3 kΩ, and the supply voltage is +10 V, find Vref.

A unity-gain inverting summing amplifier has 3 inputs: V1 = 1V, V2 = 2V, V3 = -3V. All resistors are equal (Rf = Rin). Find the output voltage.
