Team Members P’ Mint P’ Pump
Weekly Progress
On Thursday 15 March 2012 My group discussion from function of kettle circuit and write new
block diagram of my product. Summary of the workgroup I assigned analyze comparator circuit and
hysteresis.
Hysteresis can be used to filter signals so that the output reacts slowly by taking recent history
into account.
In product use thermostat controlling a heater may turn the heater on when the temperature
drops below A degrees, but not turn it off until the temperature rises above B degrees. This
thermostat has hysteresis.
Thus the on/off output of the thermostat to the heater when the temperature is between A and B
depends on the history of the temperature.
This prevents rapid switching on and off as the temperature drifts around the set point.
Fig. 1. Sharp hysteresis loop of a Schmitt trigger Fig. 2. Non-inverting Comparator with
Hysteresis
Engineering Analysis
Strong Point
- Can assign temperature from calculate circuit.
Weak Point
- Use 2 input only if don’t application.
Next Week Job
- My group will combined circuits.
