Electronics and Communication Power Electronics Difficulty: Medium

Consider the circuit shown in the figure with input V(t) in volts. The sinusoidal steady state current I(t) flowing through the circuit is shown graphically (where t is in seconds). The circuit element Z can be . . . . . . . . A debouncing circuit is Let $$g\left( t \right) = {e^{ - \pi {t^2}}}$$ and h(t) is a filter matched to g(t). If g(t) is applied as input to h(t), then the Fourier transform of the output is B-frame is also known as If m t is modulation index of FM. What is the value of ratio $$\frac{{{{\left( {\frac{{\text{S}}}{{\text{N}}}} \right)}_{{\text{WBFM}}}}}}{{{{\left( {\frac{{\text{S}}}{{\text{N}}}} \right)}_{{\text{AM}}}}}}$$ for 100% amplitude modulation with identical total transmitted power?
