    With the aid of block diagram,explain the working of Heterodyne spectrum analyser

    A wave analyser using the Heterodyning principle is shown in the block diagram of fig.In this,the input signal to be analysed is Heterodyned to a higher intermediate frequency (IF) by an internal local oscillator.Tuning the local oscillator transfers the various signal frequency components into the passband of the IF amplifier. The working frequency range of…
