A diode detector is used to detect an amplitude modulated wave of modulation by using a condenser of capacity in parallel with a load resistance kilo ohm. Find the maximum modulated frequency which could be detected by it.
Step 1. Given data:
Step 2. Formula used:
For a combination of resistance and capacitance,
Frequency can be given as: , where resistance, capacitence, modulation.
Step 3. Calculating frequency
Putting the given values in the above equation, we get
Hence, the maximum modulated frequency that could be detected by it is .
