A diode detector is used to detect an amplitude modulated wave of 60% modulation by using a condenser of capacity 250pF in parallel with a load resistance 100 kilo ohm. Find the maximum modulated frequency which could be detected by it.

The frequency is given by: \(f=\frac{1}{2\pi \mu \tau }\) For a combination of resistance and capacitance is given by, τ =RC substituting in the above equation \(f=\frac{1}{2\pi \mu RC}\) μ=0.6 , R=100KΩ , C=250×10−12F \(f=\frac{1}{9.42*10^{-5}}=10.61KHz\)
