Following are the Difference between Voltage comparator and Schmitt trigger.
|Voltage Comparator has only one reference voltage.
||It has two reference voltage utp and VLlt.
|The input voltage applied to the non-inverting input and the fixed reference voltage to the inverting input and vice-versa.
||The time varying input voltage is applied to the inverting input and the feedback voltage to the non-inverting input.
|It is open loop system.
||It is closed loop system.
|It does not exhibit Hystersis.
||Schmitt Trigger has Hystersis Characteristics.
|It is used as zero crossing detector, variable threshold detector, level detector, peak-to-peak detector, phase detector, interfacing sense
amplifier and pulse height discriminator.
|It is used as a wave shaping circuit, level detector and pulse-height discriminator. Its main use is to convert any kind of wave into
