WebIt means that a DSBSC signal is obtained by simply multiplying modulating signal (V m sin ω m t) with carrier signal (V c sin ω c t). This is achieved by a product modulator. The block diagram of a product modulator is depicted in Fig. 22.32. Here we will discuss two types of product modulators namely the balanced modulator and ring modulator. WebA simple form of AM is the Double Sideband (DSB) Modulation, which typically consists of two frequency-shifted copies of a modulated signal on either side of a carrier frequency. More precisely this is referred to as a DSB Suppressed Carrier, and is defined as f ( n) = m ( n) cos ( 2 π f 0 n / f s) images of pretty japanese women
