How does a square law detector work?
Working Operation
In every positive half cycle of the input, the demodulator diode is forward biased and charge the filter capacitor C connected across the load resistance R to almost the peak value of the input voltage. As soon as the capacitor charges to the peak value, the diode stop conducting .
What is Square Law diode detector?
In electronic signal processing, a square law detector is a device that produces an output proportional to the square of some input.
What is Square law response?
a square law response, where. Vout. = k Pi. At higher RF voltage, above the knee, the output voltage is approximately the peak of the RF voltage, proportional to the square of the power.
Why detector is required to have a square law response?
The square law detector circuit is used for detecting modulated signal of small magnitude so that the operating region may be restricted to the non-linear portion of the V-I Characteristics of the device.
